I wanted the best
I liked Steeda's intake because it's the only one with this airbox that routes the factory air intake in the radiator support. The cheap ebay ones are just sitting in the engine compartment. I am a little surprised about noise.. It's not as noisy as I thought it would be based on other turbo cars I've owned in the past. I am getting a little bit of a louder "stu-tu-tu-tu" when I rev the motor a little bit, but it's not obnoxious. My only criticisms are that the 45 degree coupler is a little bit long... I will trim it in the future. I also had to hammer in a very small dent on the backside to create a smidge of clearance for an AC compressor line. I have hood struts already so I didn't have to worry about the hood prop being in the way.

Great Sound, Easy Install.
The Steeda Team really hit the mark with this intake kit. The build quality makes it a great value compared to other options out there for the Focus ST. Easily mounts right into where the stock air tube and box come out from. Adds a throaty sound and unmasks some of the turbo noise. Fit and finish is good, but the hood prop rod can't latch into place with the aftermarket airbox, not a huge deal. Overall, for the price and especially if you get it on sale, this is a great intake system for the Focus ST.

Best CAI out there.
Best CAI out there? Well look at the design. Everyone on the internet talks about upgrading factory tubing all over the ST minus the factory piping from the grill. to the intake. Even Steeda will say the Ford did a good job with the ST piping , but when it came time to design a CAI for the ST they separated them selves from all the other CAI builders by removing the factory piping and linking the box to the grill where the air comes from. The intake pipe from the coupler to the turbo is basic and fits great. There is a difference in the feel of the car with the stock tune, but the real performance benefit will come with a tune. Steeda has the dyno test results showing stock, Steeda tuned, and Steeda tuned with CAI to back the numbers. Awesome!!!

Great performance and sound
You can definitely feel the power gains, but now my mpg is around 20-22 when before it was 24-26

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.
