The newly-designed ROUSH Performance Cold Air Intake for the V8 F-150 engine brings great performance increases, achieved with an installation that takes under an hour, with no calibration required! The F-150 V8 will benefit greatly from the addition of this ROUSH Cold Air Intake Kit, which provides more efficient air intake than the stock airbox. Providing much less intake restriction than stock in forced induction applications, this cold air intake kit ? the most highly-engineered kit of its kind on the market ? increases engine performance with no PCM re-calibration required! Latent potential in power and fuel efficiency that would otherwise be restricted, as well as reduced pressure drop, are two important benefits of this system. Custom tuning is not a requirement, as this CAI system was engineered and tested specifically for this application. The kit features increased inlet and airbox sizing to allow for maximum airflow, and provides an additional induction noise and aggressive performance sound. It was designed using OEM CAD data to guarantee optimized fitment, keeping heat out, and encouraging maximum performance. Our high-flow, high-capacity dry filter is proven to retain its shape. It is composed of an inner and outer layer of wire mesh for durability and reliable support of filtration media. The filter requires no oiling and is easily washable for re-use. Included in the kit is the air filter with clamp, oversized injection-molded air box tray, a clean air tube, 105mm mass airflow tube, and all required mounting hardware and instructions. The kit utilizes EPDM rubber couplers for proper fitment under engine load, rocking, and twisting, and will not void your factory warranty. Factory mounting locations and hardware are utilized to allow for quick and easy installation.
