      Boosts Horsepower. An AEM Brute Force Cold Air Intake improves the airflow into your S197 Mustang's engine for more power and better gas mileage all while filtering out harmful power robbing particles. This AEM CAI kit completely replaces your 5.0L GT Mustang's restrictive factory air box, intake tube and paper filter element with a Dryflow filter assembly for an increase of horsepower and torque.

      No Tune Required. Unlike other Cold Air Intakes on the market for the 5.0 GT Mustangs the AEM Brute Force CAI does not require a computer re-tune. The engineers at AEM designed, tuned, and dyno-tested this cold air intake to improve your Pony's power using the factory tune.

      Reusable Air Filter. AEM Dryflow air filters are made from an oil-free, synthetic filter media for outstanding air flow, filtration, and performance. They are washable and re-usable and can be used for up to 100,000 miles before servicing (depending on driving conditions).

      Made in the USA. Manufactured in the USA from CNC mandrel-bent 6061 aluminum piping to assure smooth unrestricted airflow, this AEM cold air intake tube is completed in a Gunmetal Gray powder-coated finish for long lasting corrosion resistance and impressive good looks.

      Not CARB Certified.This is not CARB certified, therefore not legal for sale or use in California, or any state adopting California's emissions standards.

      Lifetime Warranty.
      AEM is so confident in their cold air intake system that it is covered by a Lifetime Limited Warranty.

      Easy Bolt-on Installation.
      AEM Cold Air Intake kits are designed to install with just basic hand tools. No extra modifications or special tools are required for an easy 1 hour installation.

      Recommended Upgrade. Even though a re-tune is not required for operation, AmericanMuscle recommends a Bama custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) to get the best performance possible out of this cold air intake.

      Application. This AEM Gunmetal Gray Brute Force Cold Air Intake System is specifically designed to fit the 2011 to 2014 GT Mustang with the 4 valve 5.0L V8 Coyote engine and does not require re-tuning the vehicles computer for operation.

      Technical Note. This AEM Cold Air Intake is not legal for use in California or other states adopting California emission standards.

        AEM Intake Review for 2011 Mustang GT

        I give this kit a 5/5 stars. Overall, I think it is a great kit. I found the kit easy to install and the instructions to be very clear. I did not have any issues with the air box seal that a few reviewers have mentioned. When I was finishing the install, I couldn't find the filter minder part, and when I called AEM the next day, their customer service was great and took care of me right away and did two-day shipping on the part for me. It looks great in the engine bay. I do feel that throttle response has improved slightly, and possibly a little more mid-range power (this is without any custom tuning). I wasn't expecting a huge performance gain, I was looking for a totally enclosed air intake that will keep the filter isolated from any hot engine air, a reusable dryflow filter element, good fit and finish, and improved throttle response. I believe this kit delivers on all 3 of those items.

        Solid construction and easy installation

        I would recommend this to anyone looking for a CAI. It is rock solid when installed and looks great under the hood. The closed box is awesome for Florida and protects the filter from water and the filter minder that comes with the air box is something I've not seen on a CAI before.

        Brute Force CAI for 2013 GT

        The AEM Brute Force Cold Air Intake Gunmetal was just as advertised. Easy to install and all parts fit well, the instructions were done well and easy to follow step by step. Hard to determine the full effect, but this GT does rip, maybe a tune would bring out the maximum effect. Would recommend this to owners with same ponys. Jim

        Poor seal fitment

        The price was the lowest of the cold air intakes so I bought this one. But the engineers needs to go back an redesign the seal that goes into the box for the tube to be inserted into. Very poor quality of design and fitment. Had more trouble making a new seal from scratch that would work to seal the air intake box. There is an old saying you get what you pay for.

        Cold air intake

        I bought this intake because of the lower price. BUT it has some problems mostly with the seal that goes into the air box to seal the intake pipe. Very bad design, very bad. I spent more time making a new seal to work. When you buy something cheap that is what you get. My mistake trying to save a few dollars. The engineers need to go back and redesign the seal that goes into the box.

        Excellent fit, installs in about 30 minutes with simple hand tools. Power gains were recognizable off the back. Also the closed boxed system works great to deter rain from heat vents and retain oem look. I would recommend this item.

        5 2014 GT - Ken1030 Installation Time: Less than 1 Hour

        Only covered one. Glad it is a great product also.

        Chosen because it is the only one with a cover to prevent GT hood vents from leaking on the filter. I messed up the gasket due to my fault. Called them, they answered the phone and positively wanted to help with any concerns. They imediately sent me another free, even though I damaged it. Great customer care! Installation and quality is great. The grey powder coat of the tube and cover are beautiful. The box is thick and made well also. The filter condition guage is a nice touch. It all looks fantastic with the engine! Has quicker response and a little bit louder sound. Oilless filter is also a plus. It made the K& N I put on an 08 look like junk!

        4 2011 GT - Vad3r Installation Time: Afternoon

        Pretty good

        This product was very easy to install for me (novice) with exception to the included weather strip. I fought with that strip forever, and had to trim it per the instructions resulting in me cutting it a little short. No other hiccups. Car is not much louder, only noise difference I can hear is in the 3-5k rpm range when I am at WOT. Idle still smooth, not really a difference in HP (that I can tell, car has no other mods).

      I have 2014 GT. What kind of HP addition can I expect with the addition of this CAI?

      • The AEM Brute Force Cold Air Intake made 8hp/10ft/lb tq on a stock GT.

      302 boss intake manifold I currently have this CAI installed on my '14 GT... i'm looking at purchasing the 302 BOSS Intake Manifold and am wondering if they work together?

      • Unfortunately, we have not yet test fitted the AEM Brute Force Cold Air Intake with the Boss 302 Manifold. By the way the manifold sits, the intake outlet would need to be turned slightly upward, and a proper coupler would be required.
