K&N - 57-1137S
Performance Air Intake System
K&N FIPK 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.
K&N FIPK 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 a 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. K&N FIPK air intakes are CARB exempt and street legal in all 50 states.
