Not All Control Arms Are Created Equal

The problem most consumers face when purchasing suspension upgrade components for their vehicle is often whether or not they are purchasing the right product and will it live up to their performance expectations. Oftentimes, faced with cost and brand considerations, consumers may inadvertently purchase a product from a source that they think is a quality supplier/manufacturer, only to find out that the part they purchased for their American pony car lacked proper engineering and performance/safety validation, was built with substandard materials and with inferior quality processes. As a result, the “deal” they thought they had ends up being a disaster. In the ensuing paragraphs and pictures, we are going to expose a HUGE quality difference that you must consider when purchasing ANY performance part for your vehicle. Like the proverb says: “Let the Buyer Beware”…

Steeda Versus Brand X

To the average person there is probably little perceivable difference in the various suspension components that are available for a Mustang today. From an casual observation perspective, they share common mounting points – but there are an untold multitude of differences that are related to their inherent design, engineering, and materials used in fabrication that result in substantial handling, NVH (noise, vibration, and harshness), performances gains, and durability… Differences that you need to be aware of so as to maximize performance and ensure safe operation of your vehicle.

On The Right, Brand X's Super Thin Material is Failing Under Normal Use

The photo above compares the two different upper control arms for a 2005 – 2014 Ford Mustang. The upper control arm is a critical part of a Mustang’s rear suspension – properly selected and installed it reduces wheel hop and improves traction under hard acceleration. The picture with the red bushing is our regular production upper control arm (#555-4112) with our upper chassis link (#555-4027) and the part with the yellow bushing is a typical competitive part from Brand X. To the casual observer, they look somewhat similar – but there are HUGE differences in how they are engineered, constructed and how they will hold up under demanding street and track use. For one, the Steeda part is fully adjustable, allowing you to dial in the appropriate pinion angle without removing the arm from the vehicle.


Note that the material on the Steeda part is painstakingly TIG welded in the optimum locations with the exact level of weld penetration and heat application for fusing the parts together – this ensures an exceptionally strong finished component structure. Additionally, the Steeda part is stitch-welded to ensure that no warping occurs during fabrication. Sure this takes more time and cost more to construct, but the end result is a solid finished product that is structurally sound and still true to engineering specifications.

Steeda Welds

Superior TIG Steeda Welds

Note that the welds on the Brand X product have indication of less than ideal weld penetration with weld material sitting on top of the material, rather than being integrated and fusing the material together – this results in inferior strength and structural durability of the completed product as the weld lacked the heat to properly bond the parts together for maximum strength. Furthermore, the weld appearance is indicative of a quickened welding process where cost is the prime consideration verses strength. Remember, with any weld, it is the degree of weld penetration and fusion of metal that occurs that matters most – verses – the amount of weld material sitting on top of the parts being joined.

Inferior Welding

Inferior MIG Brand X Welding

Material Strength

The Brand X product lacks the heavy-duty construction of the Steeda part, with material in some key areas less than 50% of the thickness of the same area on the Steeda part. In the photos below, the Steeda bracket has a dimensional thickness of 6.39mm and the Brand X dimension is a meager 3.21mm – with the tremendous forces this part is subjected to, it is only a matter of time before the part will flex, bend, and ultimately have a catastrophic failure when the vehicle launches exceptionally hard or is subjected to the tremendous forces of track and aggressive street driving.

Brand X Uses Inferior, Thin Materials

Steeda's Materials are TWICE as Thick as Brand X


From a busing perspective, the Brand X products synthetic bushing employs a pinhole voiding feature and lacks a thrust washer to properly retain the bushing within the structural housing. The construction technique results in reduced structural durability and integrity in the long-term and is prone to excessive NVH (Noise, Vibration, Harshness) characteristics as it wears because it lacks overall structural durability and integrity.

Brand X Lacks Trust Washing, Inducing Unwanted Lateral Movement

The Steeda bushings we use in our upper control arm are a special proprietary three-piece design (see image below) we engineered and competition tested to enhance performance and reduce NVH over other inferior competitive designs. We strategically integrate a thrust washer to secure the bushing, further increasing structural integrity and providing reduced slop. Designed for demanding use on both the street and track, our part has been extensively tested on our race cars under the most severe conditions possible – all without failure and compromise!

As an additional example of the vast hidden differences in control arms today, look at the cut-away photo below in which we expose the differences in a typical non-adjustable upper rear control arm for the 1979 – 2004 Mustang in the market today. The non-Steeda control arm in this picture was installed on a street Mustang and after installation, it quickly deteriorated to the point where there was a serious “slop” in the rear suspension as the bushing in the control arm suffered wear under the stress it is subjected to. Suffice to say, with this component part, the vehicles handling capabilities and the NVH characteristics diminished ever further as the bushing prematurely failed due to its design and construction.

In the picture below, you can see how we cutaway the upper control arms to expose exactly what went wrong for everyone to see. In this case, the durometer (the measure of the hardness of the bushing) was too stiff – and this stiffness caused dramatically increased noise, vibration, and harshness to be transferred to the vehicles chassis, and in addition, with the tremendous stress the control arm is subject to, premature wear of the busing occurred that resulted in adverse handling and essentially a failure of the suspension assembly.

Steeda's Three Piece Bushing (left) Eliminates Bind Unlike Other Brands, Which are Known to Fail

In this picture, you can see just how much more thought and engineering went into what we designed, engineered, and manufactured under our strict ISO 9001-2008 manufacturing processes. We specifically designed the control arm out of lightweight aluminum, and provided increased reinforcement in key critical areas where it is subjected to extreme stress. In addition, we employ an industry exclusive design of incorporating three busing materials into one – the outer bushings (red in color) have a specific durometer rating so as to limit NVH and provide the flexibility required for suspension movement, and the center bushing (black in color) has a much higher durometer rating so that it provides the tight travel and control a reduction in lateral movement that is desired for maximum control and traction.

In addition to the obvious differences in bushings, we purposely constructed this Steeda upper control arm out of 6061 aerospace grade aluminum alloy – an alloy that affords tremendous strength and one that also dramatically reduces the un-sprung weight of the suspension. TIG welded, our control arm in this instance is 25% lighter than the factory control arm and is less than one-third the weight of competitive steel control arms. Remember, un-sprung weight is “the enemy” when it comes to suspensions as it has a negative effect on how your suspension system reacts as it encounters uneven road surfaces and in addition, it results on harsher riding conditions as the increased mass is being moved around.

In summary – not all suspension components are created alike – there are major differences in engineering, manufacturing, and material quality. So – when you set out to enhance the performance of your vehicle, remember “The Steeda Difference”.

Designed, Engineered, and manufactured under strict ISO 9001-2008 Standards and competition tested under the most grueling race conditions on the planet, the Steeda name is your GUARANTEE of quality. Made in the USA and with a lifetime guarantee – you simply cannot buy any better performance part.

You Ask, We Listen. Steeda’s New No-Compromise Rear X-Brace

Vehicle engineers around the world all know that chassis torsional rigidity is a critical factor in ensuring the optimum cornering ability of your car and how much you can accelerate into, through, and out of a turn. A stiffened chassis has a direct affect on how well your vehicle will handle when it is driven aggressively on the road, track, or at the dragstrip. The reason for this is because if your chassis is a “big wet noodle”, all the suspension tuning and roll stiffness adjustment in the world won’t function properly because your car is flexing so much. Now – Steeda Autosports is proud to announce that we have a newly engineered and hugely impactful rear X-Brace that dramatically stiffens the rear chassis area AND it allows for full retention of your rear seat!

Steeda Mustang Rear X-Brace

Contrary to common belief, there is no such thing as a chassis that doesn’t flex. When put under a load under aggressive driving on the street or the track, every vehicle chassis has a variable amount of flex – and this flexibility if left unchecked, can have a hugely detrimental effect on your ride quality, handling abilities, and your overall vehicle performance.

In essence, chassis stiffness is what separates a great car to drive from one that is merely just an OK. Lets dig into the some of the specifics about chassis stiffening and also the facts and features of the new Steeda X-Brace for the ’05 – ’14 Ford Mustang.

Steeda Mustang X-Brace

The chassis of a car is the most important structural part of your vehicle. The more rigid it is, the better chance that all of the wheels will point in the desired direction. This is a good thing for control, safety, comfort, and maximum performance. If the vehicle’s body/frame flexes too much, the wheels (and therefore the vehicle itself), will move in directions other than the one in which the driver is intending it to go in. This movement doesn’t have to be large to be noticeable or have a negative effect on overall vehicle performance. The need for constant steering corrections while driving may be due to frame flex (among many other possible causes). This can be tiring at best, and can make a car’s cornering abilities far less than optimum – another very negative performance factor. In the past, when automobile frames were less rigid than today, sports cars often had very stiff suspensions. This reduced unwanted wheel movement –but– it also reduced comfort, and, seemingly paradoxically, sometimes reduced handling abilities as well. Remember, your vehicle’s tires must be in constant contact with the ground in order to transmit acceleration, braking, or cornering forces. A suspension that is too stiff will have wheels rebounding into the air, adversely affecting road grip, handling, and performance. The speed gurus at Steeda Autosports set out to tackle this issue and with the mission to design a solution that improved chassis rigidity and also did not impact the rear seat area of a Mustang. The solution: The all-new Steeda X-Brace made for the 2005 – 2014 Ford Mustang.

Steeda Mustang X-Brace

Strategically designed, engineered, and manufactured under our strict ISO 9001:2008 Certified Standards, this chassis enhancement is designed to be mounted to the rear shock towers and offers a dramatic improvement over current competitive designs which only attach to the sheet metal behind the rear seat. The design of the Steeda X-Brace is such that the loads between the rear shocks, springs and the chassis are part of a more unified and substantial vehicle structure – not just the sheet metal of the car. Since it is mounted to the shock towers, the reaction time it has on correcting the loads at the rear of the car are dramatically reduced.

The Steeda X-Brace brace installs in the chassis area between the rear wheel wells behind the rear seat – effectively coupling this part of the rear structure together for increased chassis rigidity. Manufactured in the USA in our Valdosta Georgia facility, this X-Brace is designed for the street, track, and dragstrip.

Some Features & Benefits

  • 4130 Chrome Moly tubular steel for “HARDCORE” structural area support
  • Structural steel mounting brackets
  • A beautiful baked powder coated finish
  • Easy bolt-in or welded-in installation

Steeda Leading The Way in Focus ST Tuning

Ford has hit a home run when they brought the 2013 Focus ST with the 2.0L EcoBoost to market as it provides enthusiasts looking for increased performance and handling in a compact package the added bonus of great fuel economy. With this platform we saw the outstanding potential to take it to the next level of overall engine performance. After months of dedicated research and development, Steeda Autosports is proud to formally announce our Steeda Certified Custom Tune services for the 2.0L EcoBoost powered Focus ST.

Focus ST Custom Tuning

With the stock calibration from Ford Motor Company, we found there is a substantial amount of torque and throttle limiting pre-programmedinto the stock calibration. . In certain instances, we found that programming the PCM to open the throttle all the way could actually hurt power in the low end and midrange. So while we can make the system give us full throttle sooner, we purposely have delayed it ever so slightly – which results in higher power loads and torque production in the low end and mid-range of the power band.

With our Steeda Certified Tune Programs we provide additional horsepower and torque while providing the utmost in engine safety and reliability. Steeda Certified Custom tunes are available for 87, 91, 92, and 93 octane fuel versions.. The dyno gains shown in our graph is our tune for 92 octane or higher fuel, note that gains will be less with lower octanes tunes. As the graph below shows we achieved horsepower and torque gains throughout the entire powerband.

Focus ST Dyno Graph

Breaking down the actual peak numbers, the torque peak numbers are the result of spikes from the initial hit, so we will break down the numbers to properly illustrate the gains achieved.

Focus ST Dyno Graph Showing Torque Curve

Looking at the peak torque shown of 318, that is a false peak due to a spike from the initial boost hit. Reading the highlighted point in the run at 3100rpm, a point where measurements have now stabilized and you are getting true readings, you can see we’ve gained over 52 ft/lbs of torque and carry large torque gains through another 1,800rpm, torque stays above stock the entire run all the way through 7,000 rpm.

Focus ST Dyno Graph at Higher RPM

Focus ST Dyno Graph at Higher RPM - Click Image to Enlarge

With no spikes to worry about for horsepower readings here we have clean, easy to understand numbers. Peak-to-peak gains were just shy of 15 horsepower, but point-to-point gains are much higher. At 5,100 we see an 18+ horsepower gain, at the highlighted point at 5,700, we see over 27 horsepower. At other points lower in the powerband we have gains of over 25 horsepower. In fact the average gain between 4,000 and 6,000 is well over 20 horsepower. Gains you will feel and enjoy everytime you mash the gas pedal.

Ready to take your Focus ST to the next level? Steeda Certified Custom Tunes will take you there reliably and safely.

The Truth About Camber Caster Plates and Strut Mounts

Suspension geometry is an extremely complicated science – one that drivers can appreciate when it is “dialed-in” properly, but few really understand the technical science behind it.  Even many race teams often guess about suspension set-ups and rely in a trial and error method to obtain optimum performance for their vehicles.   Rest assured that the suspension experts at Steeda Autosports , who have been engineering and designing suspension system enhancements since 1988 for the Mustang, have a few tricks up our sleeve on how to achieve optimum Mustang performance.

One easy way to “dial-in” increased handling of your Mustang is to install a set of Mustang Camber Caster Plates or Mustang Strut Mounts and adjust your Mustang suspension so that you have more precise control of your suspensions behavior – but beware – not all Mustang Camber Caster Plates / Mustang Strut Mounts perform like they should and there are considerable differences in their engineering, component quality, and most important, their safety.

Mustang Caster Chamber Plates

Fundamentally, the idea of the Mustang Camber Caster Plates / Mustang Upper Strut Mounts is to provide increased camber and caster adjustments so that a more aggressive wheel alignment can be “dialed-in” so as to enhance a vehicles cornering or rolling ability.   The principal notion is to maintain as much tire contact as possible during aggressive street driving or whenever you are on the track and to minimize tire rolling resistance when you are at the drag strip. Following is a summary of camber and caster and how it can make a sizable difference in your cars performance:

Camber angle is the angle made by the wheels of a vehicle.  Specifically, it is the angle between the vertical axis of the wheels used for steering and the vertical axis of the vehicle when viewed from the front or the rear. If the top of the wheel is farther out than the bottom of the wheel (e.g. away from the axle), it is called positive camber; if the bottom of the wheel is farther out than the top, it is called negative camber.

Camber Diagram

Camber Diagram

The camber angle plays a key role in altering the handling capabilities of a vehicles suspension for both road racers and drag racers:

  • For Mustang road racers, negative camber improves grip when cornering. This is because it places the tire at a better angle to the road, transmitting the forces through the vertical plane of the tire rather than through a shear force across it and maintaining a proper contact patch.
  • For drag racers that want optimum straight-line acceleration, the greatest traction will be attained when the camber angle is zero and the tread is flat on the road.

Proper management of camber angle is a major factor in suspension design, and must incorporate not only idealized geometric models, but also real-life behavior of the components; flex, distortion, elasticity, etc. What was once guesswork has now become much more scientific with the use of computers, which can optimize all of the variables mathematically instead of relying on the designer’s intuitive feel and experience. As a result, the handling of cars has vastly improved over the years with dramatic results.

In cars like the Mustang that utilize a McPherson Strut front suspension, camber angle is fixed at a set degree.  The elimination of an available camber adjustment may reduce maintenance requirements, but if the car is lowered by use of  Mustang lowering springs, the camber angle will change. Excessive camber angle can lead to increased tire wear and impaired handling – a problem with may cars where their owners mix and match various components from differing suppliers in their quest to improve their suspension.

Caster angle is the angular displacement from the vertical axis of the suspension of a steered wheel measured in the longitudinal direction. It is the angle between the pivot line (the imaginary line that runs through the center of the upper ball joint to the center of the lower ball joint) and vertical. Road racers sometimes adjust their car’s caster angle to optimize their car’s handling characteristics in particular driving situations.  When a vehicle’s front suspension is aligned, caster is adjusted to achieve the self-centering action of steering, which affects the vehicle’s straight-line stability. Improper caster settings will cause the driver to move the steering wheel both into and out of each turn, making it more difficult to maintain a straight line.

Excessive caster angle will make the steering heavier and less responsive, although, in racing, large caster angles are used to improve camber gain in cornering.

Caster Diagram

If all of this sounds very confusing, worry not – because at Steeda Autosports – we take the guesswork out of dialing in your suspension and offer many great components  and alignment specifications that are specifically tuned to work together to maximize your performance.  Remember, we are not newcomers in this arena, as we have been working on improving Mustang suspensions continuously since 1988 – longer than any other Mustang performance company in history and we manufacture a comprehensive line of Camber Caster Plates and/or Upper Strut Mounts for your application.

Following are just some of the key qualities/features that we engineer and manufacture into our Mustang Camber Caster Plates that we sell:

  • We are confident with the engineering and quality of our Camber Caster Plates that we offer a free Lifetime warranty is free with ALL of our caster camber plates
  • We use a Teflon-lined spherical bearing that is entirely custom designed for our applications.  It is not an “off the shelf part” readily available – rather we took the time to have a special unique part that also provides the level of optimum performance and durability we demanded for street and track applications.
  • A special 8,000lb rated stainless steel Spirolock snap ring is used to secure the bearing into the housing – this ensure that the bearing stays where it is suppose to and not fail.
  • Our 4 bolt plates also use 7075 grade aluminum – This much higher cost aluminum alloy is strong, with a strength comparable to many high grade steels, and provides very good fatigue strength and less resistance to corrosion than many other aluminum alloys.
  • Our plates allow for independent adjustment of caster and camber for better alignment  (caster is not adjustable from the factory setting) and are a direct bolt-in application – No modifications required

In summary, the Benefits for using these plates/mounts include:

  • Dial in more negative camber for better cornering
  • Straighter tracking and better high speed stability
  • Better steering response, quicker turn in
  • Holds precise alignment in ALL driving conditions
  • Less friction than stock bushings
  • Offset bushings allow custom adjustment of strut height
  • Increase suspension travel on lowered vehicles
  • No interference with hoods or strut tower braces – a common problem with some other brands

Many people will ask us if there indeed are differences in Camber Caster Plates or Upper Strut Mounts.  Suffice to say – indeed there are.  While others may use inferior materials or assemble their parts in foreign countries or under less than ideal manufacturing conditions, at Steeda Autosports, we use only the finest materials in the construction of our parts, and we do that under strict ISO 9001-2008 Certified Standards.  Just ask around how many others do the same – and you will find out that there are no other aftermarket company that go to the extremes that we do to build quality parts here in America under strict ISO Standards.  Nobody else!

Why do we go to such extremes?  Here is an example of a very popular Camber Caster Plate from manufacturer “ABC” that a customer purchased and installed on his car. We became aware of this when recently at our Pompano Beach facility, a Mustang was towed in that had suffered a complete failure of a Camber Caster Plate with devastating results.   In this specific example, the Camber Caster Plate bearing retainer failed, causing the strut to literally punch it’s way thru the retainer and separate – you can only imagine the damage that occurred to the vehicle and the shock the driver had when it failed.  Thankfully, the driver was able to somehow maintain partial control his car and bring the car to a safe stop – nevertheless, the results could have been even more catastrophic.

Hopefully, you now have a slightly better understanding of Mustang Camber Caster Plates and Mustang Upper Strut Mounts and how that can dramatically improve the handling and performance of your Mustang.  To assist in in optimizing your vehicles performance, feel free to check out or call us at 954-960-0774 and talk to one of our Performance Experts and see what we can do to improve your vehicle’s suspension system today!

Why Steeda Cold Air Intakes Blow Away The ‘Competition’

Shopping for a Mustang Cold Air Intake and a Mustang Performance Tune should be easy – you want to purchase the best performing intake system that delivers maximum horsepower, offers great reliability, all with the highest level of quality available for your hard earned dollar. Unfortunately, the market today is full of various manufacturers and retailers that are promoting products that have inferior quality and design, do not maximize “safe” horsepower and torque, and may potentially cause more harm than good. With many retailers making claims that are often under fulfilled, the consumer today is often more challenged then they may realize in their decision making selection.

In the automotive business, you get what you pay for. If you want a cheap underperforming intake and tune – there are plenty available to choose from. But if you want a serious CAI that is designed, engineered, and manufactured under strict ISO 9001-2008 Certified standards and one that will stand up to the test of time on the track, dragstrip, or on the street – the solution is really simple – let us explain the simple truth about Mustang Cold Air Intakes and Performance Tunes:


For purposes of this review, we are comparing two very popular Cold Air Intakes (CAI) that are available in the market today: The Steeda ProFlow Cold Air Intake and another CAI from a manufacturer we will politely refer to as being from “J”. The “J” CAI is often blogged about as being a good intake for the money. But when you do a detailed engineering review of the intake and explore their inner elements – you will be shocked by what you will discover and how you have been mislead by marketing hype and salesmanship.

The photo above is of the Steeda ProFlow CAI. Note the stainless steel construction of the housing that separates the incoming air from the engine compartment. This extremely durable housing is topped off with a soft/pliable yet tough neoprene synthetic rubber that forms a tight seal against the vehicle hood – effectively stopping unwanted hot engine compartment air from entering the air box. The air filter is a special composite nano-particle element that is extremely effective at stopping ambient debris and dirt – yet it also allows for maximum air-flow by being less restrictive than most other filters on the market. This filter incorporates a special inner pleating design that affords maximum surface area – key for ensuring a smooth and uninterrupted flow of incoming air.

A design element we have incorporated into this CAI is our exclusive aluminum velocity stack component that we developed directly from feedback and tests from our factory sponsored Mustang racing program.

This velocity stack serves multiple purposes – primarily to ensure a smooth airflow across the Mass Air sensor so that its readings are not compromised, and also to provide a denser flow of fresh incoming air. Sure it costs much-much more to include a part of this design, yet alone a part made of aircraft grade aluminum, but when you set out to design and engineer the best CAI possible, this is an example of the key details and expense you include in your product. Securely fitted to the velocity stack is a durable silicone connector with dual stainless steel band clamps that attaches our roto-molded inlet tube with our proprietary cool-tube technology. Together these components provide an extremely smooth transition for incoming air to enter the engine’s intake manifold.

To the novice, the Cold Air Intake from “J” is superficially similar in appearance – being comprised of an airbox, filter media, and an inlet tube. However, that is where the similarities end. When you look real close at the design of the airbox housing, note that there is an inherent design flaw that does not completely seal the airbox from the engine compartment – a flaw that will certainly allow unwanted hot engine compartment heat to enter the airbox. When you cutaway the various components, note the connection between the air filter and the intake tube….this slip on connection has the inlet tube sticking out directly into the path of the incoming air – forming a pronounced step that is essentially a built-in turbulence generator. This will precipitate an increase in turbulence of the flow of the incoming air.

This turbulence occurs at one of the most critical areas of the CAI – just upstream of the Mass Air Flow sensor….not a good thing for maximizing efficiency or performance.

In addition, there is the strong likelihood for a mistake to occur during installation in that this design has no real built in “stops” provided to set the two pieces in the optimum position. The potential exists where the pieces could be slid too close together causing the inlet tube to protrude even further into the incoming airflow causing an even more turbulence into the incoming airflow.

From a design, engineering and construction perspective you can readily see that there indeed is a substantial difference in Cold Air Intakes in their engineering. These differences can and will have a dramatic affect on your vehicles performance.

Now – lets test these two Cold Air Intakes and document the actual differences under real world testing:

Testing Performance

Most people think the intention of a Cold Air Intake is to feed your engine with a clean fresh and cool supply of air for peak performance, and they are partially right. Everyone knows that cooler – denser incoming air is a key ingredient for maximizing horsepower and overall performance of your engine. However no one thinks about maximizing airflow AND velocity for the best overall performance. This is a key factor Steeda Autosports does not overlook.

Bigger is not always better. It takes careful design and understanding of airflow to design a performance intake. Just throwing the largest mass air housing you can put on a car isn’t going to automatically produce the best power under the curve. In many cases it can actually hurt power. Precisely matching MAF size along with our velocity stack helps preserve velocity, which avoids negatively affecting throttle response and low end torque. This means better low end power production and better overall response and feel.

In an effort to test the effectiveness of both the Steeda and the ‘J’ CAI, we embarked on a series of tests including dyno testing and real world thermo tests that would effectively and accurately provide quantitative data that would reveal the performance of each intake. Our research for each CAI was performed on the same 2011 Mustang GT and under as identical conditions as possible (e.g. driven over the same routes, same traffic conditions, same car and dyno on the same day for all dyno testing, etc.) using temperature data collected from the vehicle’s ECU as well as our own temperature gathering equipment.

First up is the dyno testing. Testing was done at a full operating temperature. The Steeda Cold Air is shown in run number one. We then immediately removed the Steeda cold air, installed the competitor ‘J’ cold air and installed a new tune that only accounted for the airflow curve of the competitors cold air, all other parameters including ignition and camshaft timing remained the same.

As you can see, the oversized housing of the ‘J’ cold air suffers from a serious lack of low end torque compared to our optimally designed system. From 2200 all the way to 3500 we make more low end torque. You will feel this extra low end torque when driving the vehicle and throttle response will be noticeably better as well. You can also see the extra size did not provide any kind of top end horsepower advantage whatsoever. In fact we averaged more horsepower over the last 1400rpm even through our MAF size is smaller than brand ‘J’. Bigger is not always better, and in this case it is not better in any way.

Now we are going to move on to the thermal tests where we compared inlet air temperatures under real world conditions. Here are the results we discovered:


For the Steeda Cold Air Intake outside ambient temp was 82 degrees – average coolant temperature was 192.48 degrees. Our air charge temperature for this test with a 30 second data log, was 86 degrees. The Air temperature differential was a mere 4 degrees above ambient air temperatures.

For the “J” CAI test outside ambient temperature rose only slightly to 83 degrees (a 1 degree increase) and average coolant temperature was 193.22. Air charge temperature for this test for the 30 second log was 100.4 degrees. The end result was staggering with the air temperature differential was an alarming 17.4 degrees above ambient air temperatures.

Result summary: Test #1 won by Steeda with only 4 degree increase – “J” looses with a 17 degree increase.


For this test we did our best to keep coolant temps as close to each other as possible by driving the exact route in the same level of traffic. Ambient air temperatures were a constant 83 degrees for both tests.

For the Steeda ProFlow CAI test after driving the car for some simulated city traffic heat soak we initiated the test. Average coolant temp on this test 190.05. At the start of the test air charge temp had risen to a max of 114.8. Speed was brought up to 45mph. The temperature dropped to a low point of 89.6 degrees in 45 seconds and remained there. A 25.2 degree drop and a temperature of only 6.6 degrees above ambient air temperatures.

For the “J” Cold Air test, we proceeded to duplicate the identical test procedure as the Steeda CAI was put through. Average coolant temp was 192.28. At the start of the test air charge temp had risen to a max of 122.00. – a net of 7.2 degrees hotter than our Steeda ProFlow CAI. Vehicle speed was brought up to 45mph and the incoming air temperature dropped to a low point of 96.8 degrees in 54 seconds. Also, a 25.2 degree drop, but still 7.2 degrees hotter than the Steeda ProFlow intake, and 13.8 degrees above ambient temperature.

Result summary: Test #2 won by Steeda with only 6.6 degree increase – “J” looses with a 13.8 degree increase.

Overall the “J” CAI consistently exhibited higher air charge temperatures across the board in all of our tests. With an outside ambient temperature differential of only 1 degree throughout the test and relatively comparable coolant temps at speed and nearly identical coolant temps at idle, the difference in intake performance was substantial with the Steeda ProFlow Air Intake consistently outperformed the “J” CAI under ALL conditions.


Our warranty program is comprehensive and complete. We have a LIFETIME Warranty on our Cold Air Intakes. If anything fails, we stand behind it completely. PERIOD. No fine print, no red tape, no bul#$%^, just a complete full manufacturers warranty that you can go to the bank with!

Remember, the Steeda Design, Engineering and Manufacturing Teams stand behind all of the products and services that they provide. In the unlikely event that a customer has an issue with any of our products, we are fully committed to work with them to resolve their concerns to their and our mutual satisfaction. We have built our rock-solid reputation over the years on superb design, comprehensive engineering, quality manufacturing and on customer service — the result is our products just don’t cause issues – PERIOD.

We purposely go the extra lengths to ensure that our products do not compromise the OEM reliability elements and we pay particular attention not only to NVH factors, but also to how the parts/tune integrate into the Ford vehicle they are engineered for. Few – if any – of the other aftermarket companies do the same degree of engineering that we do…and none of this group are ISO 9001-2008 Certified like we are.

Performance Tunes

Much can be said about performance tuning and the amount of torque and horsepower that they develop. Inevitably, the discussion always ends up being about will the consumer need to purchase additional tunes as additional modifications are made –or– the discussion is about warranty implications and what would happen if a catastrophic failure occurs….and rightfully so. Shamefully, there are plenty of self-taught tuners, tuners that rely on trial and error, and others that profess to be skilled at tuning based on using customers cars as their test fleet, acquiring information and “perfecting” their abilities as they conduct business. Professional tuning is much more than just passion of a novice in the industry – rather it is a dedicated and extremely complicated science where there is no room for error.

At Steeda Autosports, we do not experiment with customer cars or learn as we go practicing a “trial and error” methodology. While other tuners may “shut off” engine key sensor inputs or purposely trick sensor readings that the ECU reads, we work with the existing Ford ECU logic and all of the OEM sensors in an extremely complicated and very technical manner so that the integrity of the vehicle is not compromised – but at the same time your power is maximized. There are plenty of tunes available from various sources that compromise the integrity of the mustang powertrain, and as a result, can cause catastrophic damage to your vehicle. Proper tuning is not only an art form, but it is also a highly technical science that requires much more than a simple handheld tuner and sloppy guesswork. In our shops we have corrected untold numbers of tunes from others – but when have you ever heard of a problem with a Steeda tune?

Our performance tunes have a dialed in safety factor – one that is intended to ensure that maximum power is provided and also to ensure that your engine is not endangered or put to the point where damage may occur. A Steeda performance tune is not done with guesswork or by trial and error – rather with our outstanding relationship with Ford Motor Company as well a with SCT, we have been able to develop a comprehensive array of tunes that are failsafe.

Check our performance history both on and off the racetrack, check the forums and see what people say about us, and lastly, check with Ford Motor Company – you will see that there is an exceptionally high level of trust in what we do and in our reputation for enhancing the performance of Ford vehicles.


Steeda Autosports is not just some new company that has appeared on the scene recently, or is a store front for mass merchandising products that others produce overseas. Rather, we have worked for over 24 years in the aftermarket industry dedicated solely to enhancing the performance level of Ford Motor Company vehicles. We have collaborated extensively with Ford, worked on programs for the Ford Special Vehicle Team and mainstream Ford Product Development, and supply performance parts to Ford Racing. We stand on our reputation, past and current successes, and our ongoing commitment to produce the highest quality parts and tunes possible. Being an ISO 9001-2008 Company is not just a trophy given to anyone that applies for it. For Steeda it means we have demonstrated our commitment to making performance parts at the highest quality level possible and for exceeding our customers’ expectations. ISO 9001-2008 Certification represents not only a significant financial investment we have made, but it is also an investment we have made so our customers can have the assurance and piece of mind when they purchase our products that they will perform the way they were intended to do so, and without causing harm to the vehicle.
