Air Cleaner Assembly

The K&N RK-3930X Air Intake System was designed to get more horsepower from your Twin Cam Harley-Davidson engine. By utilizing the stock air cleaner cover, the factory look is retained. Built around the legendary K&N High-Flow Air Filter, this RK Series assembly includes an innovative powder coated billet aluminum back plate 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. The RK-39130X comes with a larger air filter and longer spacers than the RK-3930.
