    Airflow Equals Performance!

    K&N's 57 Series Fuel-Injected Performance Kit (FIPK) Air Intake Systems are designed to reduce air intake restriction and are proven to improve airflow over factory air filter assemblies.

    Air is directed through an aerodynamic intake tube into the throttle body to produce guaranteed increases in power and acceleration throughout the engine’s RPM range. The intake tube is designed to accommodate the factory air temperature sensor and comes complete with an oversized cone-shaped air filter that can be used for up to 100,000 miles.

    Quick and easy installation, using your vehicle’s existing factory mounting points. Street legal in all 50 US states.


    • Rotationally-Molded HDPE/Black Plastic Tubing

    • Guaranteed Horsepower & Torque Gains
    • Reusable Cotton Gauze Filter
