Product details
K&N AirCharger Air Intakes replace the restrictive stock OE air cleaner with a K&N High-Flow Air Filter and mandrel-bent aluminum intake tube. The efficient design provides your Harley with significantly more airflow, resulting in additional power. These air intakes come with a billet aluminum throttle-body mounting plate and mounting hardware. Each of these air intakes comes with a washable, reusable K&N high-flow air filter, backed by the Million Mile Limited Warranty. Installation is so easy, most intakes can be installed in 90 minutes or less. The sleek styling gives your Harley that coveted custom look while increasing performance. K&N AirCharger Air Intakes for select Harley-Davidson Touring, Softail, Twin-Cam & Sportster motorcycle models increase power by eliminating the restrictive stock air cleaner and replacing it with a low restriction intake.
