The RK-3909 assembly has a powder-coated billet aluminum backing plate with a built-in dyno-tuned velocity stack.

The RK-3910, a large capacity, custom assembly for Twin Cam Harley Davidson motorcycles, has been developed around an original oversized K&N High-Flow Air Filter. This air cleaner assembly has a taller air filter for Harley owners that bore and stroke their motors. This assembly boosts performance and service intervals. K&N Engineering designed the RK-3910 with a powder coated, billet aluminum backing plate. The RK-3910 features a built-in, dyno-tuned velocity stack. This vents the vapors from the crank case into the intake air stream.

Twin cam Harley Davidson owners can convert their RK-3909 air filter assembly with the RT-3910 custom assembly filter kit. The RT-3910 comes with a taller K&N air filter and longer spacers and is a cost effective way of getting more performance.

K&N's Aircharger Performance Intake System will get more horsepower from your Haley-Davidson motorcycle. These High-Flow Intake Systems increase power by eliminating the restrictive stock OE air cleaner and replacing it with a K&N aluminum intake tube. This complete intake system will help relieve the laborer feeling associated with two-up riding of loaded touring. K&N High-Flow Intake Systems give Harley-Davidson motorcycles an aggressive appearance while providing a significant increase in airflow resulting in more power.
