K&N has been the world's leader in washable, reusable performance air filters since 1969. From the legendary cone filter to complete cold-air intake systems, K&N's cotton-gauze element delivers more airflow than paper while staying serviceable for the life of the vehicle.
Give your 2001-2017 Harley-Davidson Softail or Dyna motorcycle a performance boost and a striking visual upgrade with the K&N 57-1137S FIPK (Fuel Injection Performance Kit) air intake system in a sleek silver finish. This performance kit is meticulously designed to replace your stock air cleaner, unlocking substantial gains in horsepower and torque for a more dynamic ride.
The K&N 57-1137S features a high-flow, washable, and reusable K&N air filter, coupled with a custom-engineered intake tube, all finished in a stylish silver.

The outcome is a tangible increase in power and acceleration across the entire RPM range, making your Harley feel more potent and responsive.
