  • This K&N FIPK kit will provide a noticeable performance increase of the 5.4L V8 that powers the 2004+ F150 trucks. How much of an increase you ask? When K&N dyno tested this FIPK system on a 2004 F150 they were able to gain 15.47 HP at 3829 RPM! K&N intake systems replace your vehicles restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicles engine to inhale a larger volume of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engines RPM range. The filters on these kits are washable and reusable. Most of our intake kits are relatively easy to install using tools commonly available.

    K&N FIPK Intake Systems replace the air box and the restriction. K&N FIPK vary in design because each kit is engineered to fit a particular make, model and year of vehicle. FIPK air intake systems use a 360 degree, Filtercharger element which provides increased surface area to promote air flow. This allows the vehicle to use all the air the engine can physically use. Unlike many restrictive factory intake plenums and filters, K&Ns FIPK intake systems drastically reduce restriction while smoothing and straightening the air flow. FIPK kits allow your engine to ingest greater volumes of air which ensures usable power and torque throughout its entire rpm range. If your engine is turbocharged or supercharged, the power gains can be phenomenal because these engines are very sensitive to intake air flow. - EMISSIONS LEGAL! K&N FIPK Intake Systems are 100% legal for sale and use on pollution controlled vehicles in all 50 United States of America. This 57-2556 FIPK system carries the K&N One-Million Mile Warranty!
