      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.

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

        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!

        Cold air intake

        Had no problems on the installation! Runs and works smoothly, you can totally hear and feel the difference! I paired it up with a bypass valve and a cat back exhaust on my 2018 ecoboost.

        5 2018 EcoBoost - AntoniusA Installation Time: Less than 1 Hour

        Roush Cold Air Intake

        Definitely one of the easiest installs on my car following my exhaust that I did about a month ago. The PVC connection was a little tricky however with the use of needle nose pliers in the right angle it pops right off. Everything else is pretty straightforward with the rest of the install. On initial start up sound pretty quiet however after a couple of pools it really woke the engine up. The turbo seems a bit laggy in the lower RPMs compared to the stock box with a drop in filter but after about 2500 to 3000 RPMs it wakes up and goes. Paired with any blow off valve and a good cat back or full exhaust is really going to wake up your ecboost! The install can definitely be done with one person however it’s a lot faster with two sets of hands especially when you are installing the new air tube and connecting it to the turbo. Overall I’m definitely pleased with the purchase.

        Perfect fit, easy install

        The air intake is very easy to install, the quality of it is really good too. The aur filter is very nice and good quality. It's a dry filter so there's no need to lubricate it after each clean.

        5 2019 EcoBoost - Detraumatize Installation Time: Less than 1 Hour

        Noticeable difference

        I was hesitant on the item based off of reviews I had read in forums and the trouble our engines have with heat soak. I noticed about 4 more mpg and a difference in throttle response as well. The shifting seems to be smoother and it feels like there’s more torque. And yes it makes the whoosh sound. In the end, I’m satisfied with my purchase and I feel like others would be as well. But it’s all off preference.

      how much better performance with optional tune and which tuner is reccomended

      • Power gains with a tune will depend on octane rating selected and additional modifications performed. We recommend consulting with the company writing the tunes to confirm power gains with their tunes.

      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
