    More Power for Better Performance. Increase the power and performance of your 2018-2019 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 2018-2019 GT Mustangs equipped with the Coyote 5.0L DOHC V8 engine. No computer re-tuning required for operation.

        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.

        Helpful (3)

        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.

            Glad I bought this intake

            I ordered this cold air intake along with a VMP tune. Had the intake installed professionally today. Have not received the tune yet. I didn’t expect much improvement over the factory intake. The car sounds better now with the roush intake. Driving the car is more fun. Throttle response is better and the car feels like it wants to go like heck. It feels more aggressive. I haven’t put too many miles on it yet. But it definitely feels like it’s quicker. I can’t wait for the VMP tune. This car is going to be a lot of fun.

            ROUSH!!!

            Easy install. Really nice looking quality. I read alot of reviews before putting it in, so I made improvements before hand. I used metal duct insulation tape to cover the gaps and seal it up around the tube. You can't see any tape so its nice and clean looking. I also recomend just giving the sound tube a good tug and it'll pop off. No need to remove that bolt, it doesn't do anything. Definitely feel the gains, especially with a tune.

            Great intake with options

            Very well put together, with a sleek look and easy install. Gives you the option to require a tune or leave ECU stock. My only dislike of it is the air box is very large. Forcing you to either cut the engine cowling, remove it, or what I did, install a spacer.

            Subpar Quality

            Went to mustang shop to have this installed. Intake came with scratched up parts and missing a seal. Called american muscle and they are trying make it right by sourcing a seal. Performance wise, the intake temps are much higher than stock and engine hesitates when accelerating. I am not running a tune and have insert installed. Roush claims that the intake will work fine without tune. Also the hood does not close properly with this intake. Have to close hood with more force than before. Hood sitting 1-2mm higher on driver side. I expected more from Roush as far as RandD of this intake. I did not see much improvement of power of this intake and it actually loses power in lower RPMs.

            Not as pictured in catalog

            I received the part and had it installed by Ford dealership. Shop initially thought that I had brought wrong model for 2018 GT. After install I had to add a vacuum cap to a extra tube on elbow that had nothing to connect to. A/M customer service told me it was one of the units meant to also fit the 2015 year model which had an extra tube to attach. Purchase was not as shown in catalog. Car runs great and pick up of HP is noticeable.

            Should be renamed to Hot Air Intake.

            Since the air box is not even slightly sealed, warm air from the engine compartment is entering the box from all sides. Looks god, but is poorly designed.

            great for no tune

            bought this intake because didn't want to void the warranty on the mustang but the fitment was great and the install was very easy. in terms of power gains the throttle response is way better and allows the engine to really breathe. the reason I give it four stars is because at idle the inlet temp goes way up not the biggest fan of that. but other than that this is a great cai paired with my roush catback

            Roush Cold Air Intake

            Very easy install. However mine came with more ports than hoses. I had to buy a vacuum plug. Also no template for cutting the engine cover. I didn’t cut it but did put the cove back on. I think it looks better, and it still the hood closes.

            Great buy!!!

            The install was very simple, the video shows you step by step on how to take out the old one and put in the new one. The only thing the video doesnt show you is how to remove the sound hose but its a very simple removal and the kit comes with a rubber plug. You can definitely feel extra power!

            Roush Cold Air Intake

            Had problems with the first air intake that I put in. It kept going into limp mode. But without any problems from American Muscle, they exchanged and sent me a new one. I put it in myself, and runs great. I did order a tuner, coming in tomorrow, to see if it helps with the gears shifting so hard. It should help. But either way. Love the way it looks under the hood. Definitely have more to add.

            Easy to install but no help on the cutout

            This is a really straight-forward installation. No special tools and no fitment issues. However, if you want to reinstall the engine cover you will have to cut corner of it so it clears the airbox. I saw a post where someone said that you could space the mounting brackets for the cover. Not on my car you couldn't. Plan on cutting the cover to reinstall it. Also, the plug for the sound tube does not fit my 19 GT. so I plugged the end of the tube with the cap from a bottle I found that fit. I honestly don't feel and difference in performance so I recommend buying a tune from Bama along with the cold air kit. That combo you will definitely feel.

            Limp Mode

            Even though it comes with an insert, my car went into Limp mode (See Manual warning with a yellow wrench in the dash and loss if power) every time I hit 70mph. Just be aware, this does require a tune for proper function.

            Great so far

            Like how it comes with the sleeve inside to use with no time till my warranty goes up. Deleted the sound tube and can still hear the intake hiss when putting the pedal down. Didn't have to cut the engine cover as I used washers to slightly raise it. Pretty great so far.

            DOES NEED A TUNE

            Looks great but as soon as I put it in the car it started running sluggish, ran with it for 2 days and as soon as i opened it up the car went into limp mode. I took the intake out and put the stock on back in and it runs perfect again. I recommend putting a tune in with this intake even though it says you don't need one. For those of us that aren't ready to void the warranty by putting a tune in the car this may not be the one for you.
