    K&N Custom Assembly KRK-3930
    K&N Custom Assembly KRK-3930

    The K&N RK-3930 Air Intake System was designed to get more horsepower from your Twin Cam Harley-Davidson engine. Built around the legendary K&N High-Flow Air Filter, this RK Series assembly includes an innovative powder- coated billet aluminium backplate that eliminates external breathers and features a built-in, dyno-tuned velocity stack. The result is a significant airflow increase to the engine without sacrificing filtration. This RK Series assembly retains a factory appearance by utilizing the stock air cleaner cover.

    • Washable and reusable.
    • Fits inside stock cover.
    • Provides increased airflow.
