The MK3 2013-2018 Ford Focus ST is a fantastic performance platform that while already very good, can still be taken to the next level. Take the intake system of your 2.0L EcoBoost Focus ST to the next level with our in-house designed, tested, and manufactured Steeda Focus ST Cold Air Intake.

This Steeda Focus ST Cold Air Intake for 2013-2016 Focus ST does not require any ECM tuning making it an easy direct bolt on. With peak to peak gains of 10 horsepower at the wheels and max gains of up to 16 horsepower, these are performance gains you will definitely feel. Our system incorporates a roto-molded thermoplastic airbox, a precision-molded thermoplastic velocity stack, a high-flow serviceable air filter, and a silicone intake tube.

Lower IATs. The Steeda cold air intake gives your Mk3 Focus better intake air temperatures, this results in better performance and improved fuel economy. The lower IATs are a result of the design of the airbox, high flow filter, and the precision-molded thermoplastic velocity stack. The airbox was designed to utilize the cold air feed coming from the grille while sealing directly to the hood liner to ensure a cool, dense air charge to the engine. 

A suggested add-on is Steeda's Focus ST Ram Air Intake Scoop for 13-18 ST.

Great Product / Horrible Instructions
I replaced a lousy CAI with the Steeda. It is an excellent product and my Focus responded well. But the instructions are terrible and it could have easily been remedied with a simple video. The rubber seal was difficult to get in place.

Cold air intake
Have the cold air intake replaced out the green filter seems to run good. Little more torque pulls strong threw rpm. I have the steeda flash, front mount, shifter sway bars with adjustable end links all from steeda very happy with there items or I would not of gone back for this. Only reason it got a 4 stars not 5 is because the silicone from air cleaner was way too long had to cut almost 1.5 inches of to make it fit properly and the hood prop rod had to bend to make fit in holder.

Works as advertised
Excellent product, probably the best CAI for the ST out there. This combined with a ram scoop (would not recommend steda's ram scoop AT All, wouldn't even fit my inlet. ) and you can notice the power difference. 10/10 on this product

Machinist and maintenance
This is a very refined product. Makes the car run much better, smooth, and quiet. Had other car people with eco-boosts checking it out.

kick ass
Got the ford racing tune only from the dealer at 13K on my 2017 ST. wow! A HUGE jump in torque! HP was not noticeable. Added the Steeda CAI about 800 miles later and noticed a huge difference in HP, turbo noise, etc. Added charge pipe and ram air and Steeda IC a few weeks later. not so much of an increase so maybe gt with cheaper versions of this. But bang for buck, well worth it. On a roll, I eat 3v's, and hang with lightly modded Yotes and the RS. The dig is a different story. lol FYI Ford Racing does NOT provide a handheld anymore so be sure you have downloaded your stock tune or make the dealer do it. I went thru the dealer on the tune and they were clueless. Get the Ford Racing tune here instead and do it yourself. I wanted to keep my warranty so I went dealer installed. I would have been better off have having jiffy lube install it. FYI after the Ford racing tune, my Cobb AP didn't work. I have no clue if car is pulling timing, A/F ratio etc, but I don't care bc of warranty.

Wow what a difference!
Last week I got to take my car to Steeda in Pompano Beach Fl. Got it back with their new tune for 2016 Focus ST's. While it was there they dyno'd it (for the tune) and installed their cold air intake. Wow what a difference! Driving around town is so much easier with the extra torque and horsepower. It kind of reminds me of my early 90's 5.0 Mustangs now. On the highway I only have to drop down one gear in situations that used to require a two gear drop. After a week of driving I'm averaging high 25's-26mpg where before I was seeing 22-23. I'm very impressed with the performance and feel of what they did. The car could have come from Ford it's so smooth. I'm glad I made the three + hour trip to let my car be their first tuned '16. Thanks to TJ Steeda for getting me set up with the right people. I hope we will do business again.

Big improvement
Once you tear out the OEM air box and the air tube to the turbo, you quickly realize how poorly designed the original parts are. After installing the new Steeda air box and tube you can now watch the needle on the boost guage dance with joy!

I bought this intake and have had it installed in my st2 now for about two months and I absolutely love it. You can definitely feel the extra power and hear the nice intake suction sound or the whoosh that everyone loves lol. Steeda is the way to go, you get what you pay for and this is definitely worth it. You wont be disappointed. Ill definitely be purchasing more products from steeda for my st soon.

Outstanding gains from go!
I've purchased other CAI Systems by another company that will remain nameless but here's a clue they have two letters in their name... Okay let me tell you about the Steeda CAI. Like I said I've installed and had a lot of CAI's over the years but the Steeda CAI is by far the best cold air induction system I've ever owned. The Steeda guys have hit it out of the park yet again. Like they say... you get what you pay for and Steeda is the best CAI I've ever used.

This plus Tuner = Thumbs up!
I bought the SCT tuner and the CAI immediately (before the Steeda tunes were out) and the mild SCT with the intake alone gave me great performace and the nice WHOOSH sound. Now I just tuned the car with Steeda's Stage 2 tune (incorporates CAI) and MAN!! 1st and 2nd are obvious smoke churners, but the increase from 3rd-4th through 4th is nuts. Two big thumbs up to Steeda on this one. And the customer service is excellent!

Awesome c.a.i.
If your in to the sweet sound of a turbo and blow off valves and increasing horsepower, then this is a necessity. I could immediately tell that this opened up the turbo. You can definitely here the turbo sucking in air and the blow off valve releasing air as you let off the throttle. Not only does the intake sound good, it adds up to 16HP! This was a fairly easy install and a good quality piece. Im very satisfied.

The CAI System is outstanding! Easy to put on yourself and immediately feel the difference once your on the road. The price might seem a little steep but you get what you pay for and this outstanding quality. The guys at Steeda know what they're doing on the Focus ST's. Thanks Steeda!

Damn Good
Not a problem with this kit, it may be a little pricey but you'll get over that when you here the engine after this upgrade. You will really feel the torque and horsepower gains from this kit. Enjoy...
