      Description

      More Power for Better Performance. Increase the power and performance of your 2018-2020 GT Mustang by upgrading to a Roush Performance Cold Air Intake. This Roush Intake replaces your GT 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 coyote powered GT without the need of reprogramming your Mustang's 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. Please note, if you would like to retain the factory engine cover on your vehicle, trimming to the cover is required.

      CARB Certified. This Roush Cold Air Intake is CARB certified and legal for use on pollution controlled motor vehicles. (D-418-13) It is intended for off road use only.

      Application. This Roush Performance Cold Air Intake kit is specially designed to fit the 2018-2020 GT Mustangs equipped with the Coyote 5.0L DOHC V8 engine. No computer re-tuning required for operation.

        Cold Air Intake

        Had the cold intake installed on my 2019 GT and it sounds slightly more throaty. Looks great and we'll see if the horse power goes up as promised.

        Roush intake

        Great product. Only this I didn't realize was I had to use a flat head and a hammer to knock out the maf sensor housing.

        Looks great, easy install

        The stock 2018-2020 air box is great, but this one looks fantastic. As it is closed, temps are as good as stock. Allows more airflow for tunes. Very easy install.

        As expected

        If you have any experience with roush you know what to expect, fit and finish is top notch. The only gripe I have is the air box is not insulated, while on the move I average air intake Temps 3 degrees over outside Temps. While sitting still Temps climb pretty rapidly, I did add a layer or heat insulating tape on the side and rear of the air box facing the engine as well as a foam seal for the air box lid as it did not have any. Overall I couldn't be happier.

        Great product, easy installation

        Great product! Simple modification of cutting the engine cover to accommodate the extra space for the new intake. I personally used a dremel tool to cut it and it worked great

        Cold air intake.

        It was easy to install and gave my mustang 5.0 about 10 mph on the top end. I also am getting 1mpg increases. I am now getting 25.5 mpg.

        Must have!

        Quality is excellent with aggressive clean look. It took little more than an hour b/c I didn't have a deep socket for the sound tube on the fire wall. Great product and would buy again from Roush.

      5 Top Rated Questions

      Will the recommended re-tune void the warranty on my 2018 Mustang GT?

      • Generally tunes will void the warranty on a vehicle. I would recommend reaching out to the dealership the vehicle was purchased from to confirm what will and won't void the factory warranty.

      What Tuner would you recommend for more gain of HP and Torque with the 2018 Roush cold air intake for the 18 mustang gt?

      • The Roush Cold Air Intake would work well with the Bama Rev-X Tuner by SCT.

      How much HP gains should I expect without a tune?

      • This will offer about 10 HP on an otherwise stock Mustang without a tune.

      Helpful (4)

      Is the tune used in the YouTube clip a tune we can get from Bama to gain 36hp?

      • The Roush Cold Air Intake was paired with a Bama Performance Custom Tune in the demonstrated video. The Bama Tunes are available for purchase to custom tune for your Mustang equipped with this intake. https://www.americanmuscle.com/2015-mustang-chips-tuners.html#shop-by1

      Can the sound delete tube be reconnected or does it have to be plugged at the firewall or tube itself? I heard that it is difficult to plug the firewall opening on kits that require it to be done. If required, is a plug provided in the kit?

      • The Roush Cold Air Intake does not have a provision for the sound tube, but will include a grommet to plug the firewall.
