K&N Custom Air Filter Assembly for Various Harley Davidson Motorcycles - RK-3932

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 this 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. The RK-3910-1 comes with a larger air filter and longer spacers than the RK-3909-1.

Benefits:

K&N's Aircharger® Performance Intake Kit will get more horsepower from your Harley-Davidson® motorcycle. K&N's air intake for Touring Models gained an estimated 12.9 horsepower at the rear wheel and K&N's air intake for Softail Models gained an estimated 10.2 horsepower. This high flow Intake System increases power by eliminating the restrictive stock OE air cleaner and replacing it with a K&N high flow air filter and mandrel bent aluminum intake tube.
