K&N AirCharger Air Intakes for select Harley-Davidson Touring, Softail, Twin-Cam and Sportster motorcycle models increase power by eliminating the restrictive stock OE air cleaner and replacing it with a K&N High-Flow Air Filter and mandril bent aluminum intake tube. These intakes comes with a billet aluminum throttle-body mounting plate and mounting hardware. K&N High-Flow Intake Systems gives your Harley an aggressive appearance while providing a significant increase in airflow resulting in more power.
