    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.

    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.

    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.

      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.

      Pretty straight forward install with the video. Getting the nut off the firewall was not too difficult, found it much easier with a short box-end wrench. Installed without a tune for now. No noticeable gains but looks good.

      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.

      It's not well made

      It's nice but there is a lot of unsealed spots so the heat of the engine gets pulled in. It's actually pretty cheap. It heats up a lot when sitting.

      Alterations Required

      Looks like the hot setup. Only issue I had was you need to cut the engine cover to install it. Wasn’t something that I cared to modify so I.returned it. It’s Hard to beat any Roush performance products though. Great product.

      Good but not Great

      Overall it was an improvement. You can definitely notice the difference right away. Also, I noticed I'm getting a bit better gas millage on my car. Sucks that you have to cut your engine cover but it also kinda looks better without it. Imo do not cut you engine cover, just take it off.

      Cold Air intake looks great and did feel somewhat of a better throttle response. Only issue was removing the sound tube it's really hard to reach had to take the car to the dealership but there was no charge.

      Roush CAI

      Very happy with the purchase, was easy to instal even for a novice such as myself. 1.5hrs. My air inlet temp is typically 5 degrees over ambient now whereas it was 20 or more. The only reason it’s 4 stars instead of 5 is that when standing still or in traffic the temperature goes up dramatically as others have reported.

      2018 GT Roush CAI - Wow!

      Everything arrived on time and in excellent condition. The install was easy. Except the darn sound tube. It took a good hour to get that nut on the firewall off. I left the MAF insert in. I'm not ready for a tune yet. I could feel a definite difference in the performance. I'm looking forward to tuning after a few more mods. I love it.

      Quality

      Great oem fit and finish. Easy, no problem install. Looks good under the hood in my opinion. Airintake by itself I noticed a 2degree drop in my intake temps over the stock 19 airbox and some slight bottom end improvement. I then paired it with a lund 85 time and the car has really woke up all through the rpm range. Not a ton of performance increase by itself but pairs well with tunes.

      Roush Intake for the win

      really great put a vmp tune and gives a stupendous gain of horsepower and torque. In my opinion I would consider the Roush intake instead of the JLT intake, performance wise with a tune the Roush does a better job.
