K&N Engineering K&N Aircharger H/D Touring Models 2017-2018 Performance Air Intake System 63-1139
KN Motorcycle Air Intake Systems
Engine Cold Air Intake Performance Kit
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 cast aluminum intake tube. These intakes come with an die-cast aluminum throttle-body mounting plate and mounting hardware. K&N high-flow intake systems give your Harley an aggressive appearance while providing a significant increase in airflow resulting in more power. These K&N air intakes are street legal in most states. They are not legal for use in California and other states adopting California emission standards.
K&N AirCharger performance air intake systems increase power by eliminating the restrictive stock OE air cleaner and replacing it with a K&N complete performance intake system.
