The K&N RK-3947 High-Flow Air Intake System increases engine intake airflow and delivers more horsepower & torque to many Harley-Davidson FLT and FLH model motorcycles. The intake system increases power by eliminating the stock OE air cleaner and replacing it with a complete High-Flow Air Intake System. The intake system comes with a K&N air filter for high air flow and long service intervals. The K&N high-flow air filter is washable, reusable, pre-oiled and ready for installation.
