Performance Air Intake System
K&N FIPK air intakes for select Harley-Davidson® Touring, Softail, Twin-Cam and Sportster motorcycle models are guaranteed to increase power. They eliminate the restrictive stock OE air cleaner and replace it with a K&N high-flow air filter and mandrel bent aluminum intake tube, which allows more air to flow directly to the engine. These air intakes include a billet aluminum throttle-body mounting plate and mounting hardware. Installation couldn’t be easier; it usually takes 90 minutes or less.

OUR STORY

WHY K&N?


K&N is the home of the original red oiled air filter. In the early 1960s, two motorcycle racers, Ken Johnson and Norm McDonald (K&N), developed a ground-breaking new idea for an oiled air filter. Five decades later, K&N® is still innovating industry-leading filtration technology, and offers outstanding protection for everything from top-fuel dragsters to commuter vehicles across the globe. Thank you for helping us reach 50 years in business!
