Upgrade your 2011-2014 F-150 3.7L-V6 or F-250/F-350 Superduty 6.2L V8 with this Cold Air Intake Kit and unleash additional performance of your engine, while increasing your fuel efficiency. The kit features the ROUSH® air filter, air dam, and induction tube.

Cold air induction is a more efficient air intake method than the standard air filtering process. As a result, cold air induction can unleash the latent potential in power and fuel efficiency that is normally restrained by your stock air intake.

Air first comes into the Air Dam, which keeps out hot air from the engine compartment. The result is that the air entering the filter is cooler and dense, providing for a more potent air charge.

The ROUSH air filter media is a synthetic nano-fiber material that traps the smallest dirt particles that ordinary cotton-gauze “performance” filters can’t capture. Based on SAE standards, ROUSH air filters capture almost twice the percentage of 2 micron particulates, and more than six times the amount of 0.5 micron particulates than our competitors filters. Furthermore, ROUSH air filters are constructed using the finest materials available today, featuring a hand-poured urethane body that won’t crack, curl or shrink like other rubber or plastisol units used by our competitors. ROUSH air filtration performance is second to none. This ROUSH air filter is 100% washable, reusable and features a lifetime warranty. The ROUSH Cool Air Dam surrounds the filter, helping to keep out hot air from the engine, further maximizing performance.

Once air passed through the filter, it is taken to the engine through a Modular Intake Tube (MIT) that can improve airflow up to 400 CFM over the restrictive stock intake tube. Made from cross-linked, high-density polyethylene, the MIT straightens out air flow by providing a smooth, unrestricted path that increases air flow to the engine.

The kit includes all the necessary hardware, making it quick and easy to install.

The “ROUSH” logo is also featured on the kit, thereby stamping your truck with the mark of the leader in automotive performance. As a result, this kit not only makes your truck faster, it makes it look faster when you open your hood.
