K&N's AirCharger Performance Intake Kit will get more horsepower from your Harley-Davidson motorcycle. K&N claims to have gained 9 HP on a 1200 Sportster, 10 HP on Softails and Dyna, and an amazing 12.92 HP on a Touring model at the rear wheel. This High-Flow Intake System increases power by eliminating the restrictive stock OE air cleaner and replacing it with a K&N High-Flow Air Filter and mandrel bent aluminum intake tube. This complete intake system will help relieve the labored feeling associated with two-up riding or loaded touring. K&N's High-Flow Intake System gives an aggressive appearance while providing a significant increase in airflow resulting in more power. Kit comes complete with a billet aluminum throttle-body mounting plate, mounting hardware, your choice of a intake tube and a tapered K&N air filter. AirChargers for Sportster and Touring come with a chrome plated breather assembly. AirChargers for Softail and Dyna come with a billet aluminum breather assembly. A DryCharger sock for increased protection from the elements is available separately.
