Harley Davidson FLHR Road King (1400cc) 2008 - 2010 K&N Performance Air Filter Kit

For over 40 years K&N has been designing and manufacturing performance air filters for motorcycles. They provide a high, virtually unrestricted air flow while maintaining filtration levels critical to ensure long engine life.

The K&N RK Series assembly retains a factory appearance by utilising the stock air cleaner cover and is designed to get more horsepower from the Twin Cam Harley-Davidson engine.

This assembly includes an innovative powder coated billet aluminum back plate that eliminates external breathers and features a built-in, dyno-tuned velocity stack, resulting in a significant airflow increase to the engine without sacrificing filtration.
