K&N RK-3909 - K&N Motorcycle Air Filters Details
Harley Davidson Air Filter Kit
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.
K&N's lifetime replacement air filters are designed to increase horsepower and acceleration while providing excellent filtration. We make over 1,200 different replacement air filters for virtually every vehicle on the road. These filters are custom designed to fit into your existing factory air box. Their drop-in design means adding performance is simple. Simply remove the disposable air filter and replace it with a K&N; there is NEVER any cutting or fitting required. Our stock replacement air filters for street vehicles are covered by our famous K&N Million-Mile Limited Warranty and will be THE LAST AIR FILTER YOUR VEHICLE WILL EVER NEED.
