K & N Air Filter Replacement - 4" E-3120

Stock air filters restrict airflow and lose efficiency over time, robbing your engine of both horsepower and throttle response. The K&N E-3120 replaces that restrictive filter with a high-flow, washable design that delivers measurable gains in power while maintaining excellent filtration. Built on over 50 years of American manufacturing expertise, this filter is engineered to perform—and keep performing through countless service cycles.

Unlike disposable filters that require constant replacement, the E-3120's pleated cotton gauze media is pre-oiled, reusable, and designed for the long haul. Simply clean and re-oil when needed, and you'll maintain peak airflow and engine performance indefinitely.
