K&N RK Series Air Intake System For Harley Twin Cam

K&N's RK Series air intake systems have been developed to get more horsepower from your Harley-Davidson motorcycle. Built around the legendary K&N high-flow air filter, the 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 series assembly also retains a factory appearance by utilizing the stock air cleaner cover.

Features:

  • Complete high-flow intake assembly fits neatly behind the stock air cleaner cover
  • Replaces the stock air filter and cleaner backing plate assembly
  • Large capacity filter provides a significant increase in airflow
  • Washable, oversized K&N high-flow air filter equals longer life
  • Oversized black, powder coated aluminum backing plate provides solid mounting
  • Dyno tuned velocity stack directs airflow to engine
  • Made in the USA
