Steeda ProFlow Mustang Cold Air Intake for your S550 opens up the intake system of Ford's 5.0 powerplant and allows it to breathe much more freely than the stock intake system allows, taking your S550 Mustang GT to the next level of performance. Steeda's engineers utilized the OE cold air feed and a large surface area high-flow nano-fiber air filter, added our famous 'race tested' velocity stack entry and then designed an advanced heat shield with a durable rubber gasket to seal the shield against the vehicle's hood. Steeda's precision CNC mass air housing provides the cleanest mass air signal on the market, resulting in smooth off-throttle to on-throttle response. Steeda's S550 CAI utilizes a removable restrictor which allows you to benefit from immediate hp/tq gains, without a tune! If you're looking to squeeze out even more power from Steeda's S550 cold air intake, we offer a tune that allows you to run it without the restrictor.

Great Improvement
Great Improvement over factory. Gained some MPGs. Really helped with Intake temps. Went from 8-10 degrees about outside temp to about 4-5 degrees above outside temp during driving. The filter itself is massive!

Highly recommend this CAI to anyone looking to upgrade their CAI
Overall Impressions: The air box and elbow are molded ABS plastic and look really good..I mean like came from the Ford factory good. Also Steeda had the forethought to put a drain hole in the bottom of the box should any water make its way into the hood vent and into the box....nice! The supplied PCV couplings and velocity stack are all machined billet and are matte polished, so no buffing or polishing needed. The filter is MASSIVE! This thing could probably hold a King sized cup from Burger King. The sound! Wow...just, wow! This CAI definitely adds some grunt to the overall sound of the motor coupled with the howl from my Corsa exhaust. The intake temps were lower, I noticed 5 degrees above ambient. No driveability issues noted, throttle response is the same as stock. I'll get to a dyno at some time to run another baseline and see what I picked up. So ratings....from 1 to 5, 1 being crap to 5 being awesome: Design, fit and finish: 4.5 (due to the elbow and velocity stack not quite matching up flush) Sound: 5 Install time: 4 (only because of that damn rubber trim) Cost: 5 (compared to other CAI systems available I think the look of this one screams factory supplied part) Overall I give this a 4.75, as in almost perfect but just a few minor issues that negated a full 5. I highly recommend this CAI to anyone looking to upgrade their CAI and Steeda has AWESOME customer service.

what a great product
what a great product. i am not one to normally write reviews but when it came to this product combined with the SCT xcal 4 and tune.....I am committed 100%. First thing to know is that the tuning of the 15 is very different than previous versions and Steeda makes it intuitive, secondly having gone from stock to stock tune restricted and then steeda tune restricted i was impressed how the engine started to wake up. After all we are talking stock parameters. pull the restrictor and do the unrestricted tune and hold on for some fun. i still cant stop smiling. :-) Great job guys and l look forward to tunes for life with you as well! like i said im sold!

Wow what a difference!
Wow what a difference! I tested my quarter mile with the track app before I installed the cai. All stock ran [email protected] slightly spinning in 1st gear. The mph is the same as other automatics with 3.55s. Then I installed the cai and drove a couple of days so the computer could relearn itself. Day 2 i tested it and it ran a [email protected] spinning threw most of 1st. My mpg also increased to 24.5 from previous stock best of 22.5. Maybe the factory installed a 4 cylinder intake but this cai really did wake it up!

Very nice add-on for the Mustang
Very nice add-on for the Mustang. Install was straight-forward, but be sure that the inlet snorkel, which is reused, fits around the intake shroud. The instructions failed to detail this bit. Easy install for someone who takes the time to do it right. Intake is much louder, it sounds like a muscle car should, especially under full throttle. One thought - the intake is made of heavy plastic and the tube is metal - would have preferred a lighter weight product to not add overall weight.

Getting 3-4 mpg better mileage
The CAI was easy to install and sounds great. Combined with the tune, the car pulls much harder in the mid to upper rev range. I have had no negative side affects. I am also getting 3-4 mpg better mileage as well. I am loving it! Next up for me will be a set of Steeda springs and sway bars.

It is a masterpiece!
It is a masterpiece! Have had the luxury of getting my hands on this nice intake, along with the Steeda tunes, as soon as it arrived, gotta say its the best there is hands down. I waited months for this intake to arrive. and it sounds amazing, GAINED HELLA GRUNT!! I can pretty much haul up grades with ease. Definitely a massive difference from stock. Install does take a little effort, but with anything good comes some work.

Power gains are surprising
I installed with restrictor, I'm still waiting on my tune via email. The power gains are surprising for just a CAI more power and torque and the car just seems louder. I can wait to see how she responds with the tune it going to be nuts! Install wasn't too bad and it looks great under the hood especially with the stickers

Steeda CAI and Tune Review
Cold Air Intake: First thing first, this set was huge! When the box arrived I thought it was something my wife might have ordered or something When i opened it i was happily surprised by what all was in there as i was expecting just the cone and pipe. The filter included is HUGE like practical joke big and it has the end cap on it has more filter material allowing for even more airflow. I had a similar set up on my old 350Z and i loved the sound from it. The tubing is substantially thick plastic that seemed pretty clean on the seams and all the holes were clear of plastic and were properly sized. Another feature that I hadn't expected was the aluminum velocity stack's build quality. I was honestly expecting either plastic wrapped in a beer can or just a beer can.. When i saw the stack i was very impressed as the welds and measurements were flawless. Even the restrictor that came with it fit like a glove. Putting all these together makes for a nice package with a very high end feel, a clean look and a feeling of confidence in my purchase.

'Pro Flow' for sure!
You can definitely notice an improvement in throttle response. MPG remains unaffected and this cold air intake looks great under the hood. Thanks Steeda!
