    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.

    Features:

    • Rotationally-Molded HDPE/Black Plastic Tubing
    • Reduces Airflow Restriction
    • Guaranteed Horsepower & Torque Gains
    • Reusable Cotton Gauze Filter

    57-2561 is rated 3.0 out of 5 by 1.
    Rated 3 out of 5 by from Good but not great Looks good and installed pretty easily on my 2011 ranger. The main disapointment is that it is loud (you can hear a whirl). At a cold start it's louder than the motor and is audible from inside the cab. When the A/C kicks on it makes another noise (best way to discribe it is like an air gulp). After warming up most of the noise goes away. I have noticed a bit more horsepower but not enough to merit buying it.
