Incorporated in this kit from Roush is the air filter with clamp, injection-molded lower air box/tray with installed EPDM foam hood seal, blow molded clean air tubes and all required mounting hardware.

Rated 5 out of 5 by from Great 1st round upgrade to SR550 Ecoboost Mustang First off, I’m not at all very mechanically inclined, and made my purchase decision based on the “how to install” video fron Bill at CJPony. Must say, took me only 1.5 hr to install this system and could not be happier. For car mod newbies, you can do this! My only true challenge was disconnecting the PCV valve. Not having done that before, a little guidance on how to adjust the clip closure would have been helpful. Looks great, sounds great, definitely feel the increased HP and torque on my ‘17 Mustang. Thanks the the CJ team for a great experience.

Rated 5 out of 5 by from new attitude installed a couple of days ago. took about 2 hours. not difficult. slightly louder intake sound when you get on it. throttle seems more responsive. love the new sound, look and quality of the product.

Rated 5 out of 5 by from Awesome Mod Awesome first mod. The Roush CAI has a loud air sucking sound on a cold start and you get a whoosh sound when you step on it. My ecoboost definitively feels faster, since it also supposedly gives you 30 hp. Lastly the install was easy, about an hour. The only hard part was getting the tube off.

Rated 5 out of 5 by from Instantly noticeable throttle response! Compared to the stock intake you can hear an enormous volume of air moving. Be prepared for a huge sucking air sound when that turbo kicks in. Throttle is more responsive, puts more pep in your step. Coupled with the Roush axle-back exhaust I am having a blast and sounding more like a Mustang!

Rated 5 out of 5 by from The best mod This is the best mod you can do to an ecoboost, I installed it yeasterday and I feel i have a new car. Its unbelivable how it sounds and the power the car gets. It's so much quicker now!! I love it

Rated 5 out of 5 by from Great sound! First of all CJ Pony parts shipped the intake really fast, faster than what I expected, and I had it on my doorstep within a couple business days, so thank you for that! Installation was really easy and as soon as I turned the car on I could hear the difference. You can actually hear air being sucked in as opposed to the stock intake. On top of the sound it looks great and you can feel a little more power. I'm glad I finally bought this intake and would definitely recommend it.

Hi, Questions for my 2017 Ford Mustang Ecoboost, 1. What will give me better performance the Rush cold air kit or the Ford performance cold air intake?

Asked by: GerritM
The Ford performance intake will require a tune the Roush does not. So with the tune the Ford performance would be the better performer.

Unfortunately I cannot accurately answer your question. Without the vendor supplying any information regarding fitment for non-US Spec cars and CJ's not having a car to test parts on, we cannot confirm this part working on your vehicle at this time.
