K&N 57-1137 FIPK Performance Air Intake System for Select 2001-2017 Harley-Davidson

Fits select 2001-2017 Harley-Davidson Softail, Dyna, and Touring models.

The K&N 57-1137 FIPK (Fuel Injection Performance Kit) is engineered to replace the restrictive factory air cleaner assembly on fuel-injected Harley-Davidson motorcycles. This system features an aerodynamically designed cast aluminum intake tube and a high-flow oiled cotton gauze air filter to streamline airflow and improve engine efficiency. By reducing intake turbulence, this kit provides a measurable increase in power and improved throttle response across the RPM range.

Constructed for durability and ease of maintenance, the system includes a rugged die-cast aluminum throttle-body mounting plate that provides a secure, vibration-resistant seal. Installation is straightforward, typically completed in under 90 minutes using standard hand tools and the included mounting hardware.
