K&N FIPK Performance Air Intake System Silver - Select Harley-Davidson 2001-2017 (57-1137S)

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

The K&N 57-1137S FIPK (Fuel Injection Performance Kit) is engineered to eliminate the restriction of the factory air cleaner, allowing your engine to breathe more efficiently. This system replaces the OE assembly with a high-flow K&N air filter and a mandrel-bent cast aluminum intake tube, significantly reducing airflow turbulence to improve throttle response and power delivery. The silver finish adds a custom aesthetic to your engine while the die-cast aluminum throttle-body mounting plate ensures a secure, vibration-resistant fit.

Designed for a straightforward installation, this kit typically bolts on in 90 minutes or less using factory mounting points. The included K&N high-flow filter is washable and reusable, providing long-term filtration performance under various riding conditions.
