    More Power for Better Performance. A Roush Performance Cold Air Intake will increase the power and performance of your 2018 EcoBoost Mustang. This Roush Intake replaces your EcoBoost Mustang's restrictive stock air box and paper filter element with a high flow air box and filter assembly for a noticeable increase in horsepower, torque and throttle response.

    No Tune Required. This Roush Performance Cold Air Intake is designed to improve the performance of your EcoBoost Mustang without the need of reprogramming the computer. By utilizing state of the art computer-aided designs, this Roush Intake will increase power using the factory tune. Even though a re-tune is not required for operation, AmericanMuscle recommends a custom tune to reprogram the vehicles computer (ECU) to get the best possible performance from this intake.

    Reusable High Flow Dry Filter. The included Roush High-flow Dry Air Filter provides excellent filtration of harmful particulates. It is composed of two layers of wire mesh for durability and is proven to retain its shape even under high airflow. This dry air filter is washable and does not require oiling, saving you time and money.

    Unique Air Box Design. This Roush Cold Air Intake features a CAD-designed roto-molded intake box that draws cooler outside air via the factory cold air duct. While the unique shape of the box improves airflow around the entire filter. A cool feature of this innovative Roush Intake is the clear plastic window that not only adds eye catching under hood appeal, but makes it easy to check the filters condition with just a glance.

    Straight Forward Installation. The Roush Performance Cold Air Intake Kit is designed to install easily with just basic hand tools. No extra modifications or special tools are required for proper installation. All necessary parts and instructions are included.

    Not CARB Certified. This Roush Cold Air Intake is not CARB certified at this time, therefore it is not legal for use in California or other states adopting California emission standards. Not legal for use on pollution controlled motor vehicles; intended for off road use only.

    Application. This Roush Performance Cold Air Intake kit is specially designed to fit the 2018 EcoBoost Mustangs equipped with the turbocharged 2.3L Inline 4-cylinder engine. No computer retuning required for operation.

    Is this intake legal in Florida?

    Even though it's re-usable, do you sell replacement filters for this CAI? I'd like to keep a spare on hand, just in case.

    • Unfortunately, we do not carry the Roush replacement filters for this cold air intake. You may be able to get one directly from Roush.

    Have a question, along with a bit of info. Question is, I already have the Mishimoto Aluminum Coolant Expansion Tank installed. Will there be any problems getting the large air tube to hook up to the turbo? And the info is for anyone asking about the Roush Cold Air Intake voiding your warranty. I called my Ford service department. And he assured me, there would be no problem. He was almost giddy, wanting to see it when I get it done. I also asked if he felt I might need to have my 2.3 tuned afterwards, he said it would not be likely, since Roush specially designed it to fit the 2018 EcoBoost.

    • There should not be any fitment issue combining the expansion tank and the Roush Cold Air Intake!

    Will this void my warranty because on Roush website it says it won't? If it ever get Carb legal and I purchase it before then will they send the verification sticker?

    • This item shouldn't void your warranty, but we would recommend contacting your Ford dealer directly to see how this could affect your warranty. If this item does become CARB legal in the future, you would be able to contact Roush directly to have that sticker sent to you.

      Definitely worth the money

      Sometimes people want too much and complain about spending 400 on “plastic” come on now! It’s ROUSH! You get what you pay for and In this instance you get a lot! Not just a noticeable throttle response, better torque, better HP and better sound! All with no tune! WORTH IT!

      Wingnut's review

      Other than a lot of sweat, and a little blood, installation went pretty well. The clamp holding the air bypass valve hose, was a real pain in the butt, both taking off, and putting on. And answering my own question, there's no fitment issues at all, with the Mishimoto Aluminum Coolant Expansion Tank already installed. Took it for a test drive, and there's a noticeable change in both turbo sound and throttle response. Well worth the money!

      Great add

      I can't vouch for HP and Torque, but I can vouch for the sound of air and turbo! It made the car feel more fun just by sound alone. 1 for looks!

      Pretty Good

      I recently purchased this cold air intake. I installed it (being my first modification on the car), I thought it looked great and not huge and bulky. Overall a great product, would recommend.
