Description

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 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. This RK Series assembly retains a factory appearance by utilizing the stock air cleaner cover.

For over 50 years, K&N® has been an industry-leader in automotive filtration and technology—offering products to increase performance, protection, and longevity in thousands of vehicle applications for consumers worldwide.
