About This Product
Boost your bike's performance while maintaining a factory look with the K&N RK-Series Street Metal air cleaner assembly. This high-flow intake system is designed to fit 2013 to 2015 Softail models and allows you to re-use your stock air cleaner cover for a stealthy appearance. The kit includes a special powder-coated aluminum backplate with a Dyno-tuned internal velocity stack, built-in breathers to replace the stock external units, and an oversized K&N air filter element. K&N testing has shown significant horsepower gains across the Twin Cam range with this setup. It is a truly stealthy performance upgrade that replaces the restrictive stock filter and backplate with high-flow components and all necessary hardware.
Manufacturer part number: RK-3942.
