- High-Performance Air Filter Kit
- 1999-2012 Harley-Davidson All Twin Cam Engines
The latest addition to K&N's RK Series was developed to get more horsepower from your Twin Cam® Harley-Davidson® engine. Built around the legendary K&N High-Flow Air Filter, the new RK Series assembly includes an innovative powder coated billet aluminum 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, yet boasts superior filtration and performance with a K&N stamped laser-etched beauty ring.
