K&N 57 Series FIPK intake kits are designed to eliminate air path restriction and deliver a massive amount of air into your engine, resulting in more power! These kits start out with an extra-large, conical shaped high-flow air filter that captures and holds more dirt and flows more air than a standard K&N OE replacement filter. The filter is attached to a rationally-molded HDPE tube that's specifically shaped for your application to reduce turbulence and accelerate airflow into the engine. High strength adapters connect the K&N 57 Series FIPK intake to the engine for a secure and lasting fit. If you're looking for the best flowing, best filtering, high performance street legal air intake system, K&N 57 Series FIPK kits are the way to go!

Any parts used in any racing, competition, off-road, marine, aircraft, or industrial use will void the warranty. All K&N Filtercharger filters designed specifically for racing and off-road uses are warranted against defective materials or workmanship for one year and unlimited mileage.
