      More Power for Better Performance. A Roush Performance Cold Air Intake will increase the power and performance of your 2018-2020 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.

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 2018-2020 EcoBoost Mustangs equipped with the turbocharged 2.3L Inline 4-cylinder engine. No computer retuning required for operation.

        Roush CAI 2019 EgoBoost

        Gobbles up air like a vacuum cleaner! Adds a punch of power and torque to my dismal four banger which makes it much more enjoyable to drive now. Not sure how much more HP and TQ it makes now but my colleague who has an older camaro SS is now wary of my intentions to make his v8 look pathetic. lmao

        Installing Roush Cold Air Intake

        I followed the video step by step and to my surprise it came out perfect the very first time. It not only looks great but it seems like performance picked up a bit too. Now the look on the oil change place when they pop the hood and look for the air filter is priceless.

        Good for price

        Looks good under the hood. Easy to install (took a couple hours). Sounds like a mini tornado when starting engine cold. Has more pep now when moving. Didnt notice any extra pep off the line...probably because the tires spun. Worth the investment to me.

        Strike 2

        Strike 2. Old issue was fixed. New issue. Almost second from last step, went to install airfilter for my Roush CAI and the filter was an Airraid filter. Roush/American Muscle needs a QA dept to verify proper parts are going to the proper customer. Not sure how you mix up an airfilter. Besides that most difficult part of the install for me was getting the air bypass valve hose reconnect. After about 20mins of trying with needle nose pliers, finally got it with a pair of vice grips. Overall easy install. I'll leave a compete review after I get my Roush filter, which American Muscle said I should be getting from Roush in about 5-7 days.

        Worth it!

        The Roush Cold Air Intake, installed in a 2019 Mustang Ecoboost. The Installation is simple enough if you have the tools, time and patience. Typically it will take about an hour to install. If you’re not too knowledgeable, or don’t feel comfortable or confident installing it yourself, taking it to a reliable shop, is another option. It will likely cost around $100 and up for labor. I’d recommend taking it to a Ford dealership, if you go the shop route, as they are used to working on Mustangs, and their turbo engines. If you’re looking for what benefits if offers, by installing a Cold Air Intake, should notice a the following: A considerable difference in acceleration, and Horsepower. Though it’s not required, tuning will give you even more benefits, in regards to the previously mentioned. You should also notice an increase in your MPG, depending on how you drive. If you want to add even more of a of a benefit towards installing a Cold Air Intake, getting a less restrictive Exhaust would be recommended. Very satisfied with the overall purchase. From ordering, delivery, and installation, no hassle!

        Perfect first mod for beginners!

        I bought this as my first mod for a '19 Ecoboost. Install was a pain in the butt due to a clamp that ford provides. other that that, works great and sounds great!

      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. 1 answer
