K&N Performance Air Filter

The K&N Air Filter is a permanent hi-performance air filter that can be cleaned, re-oiled, and used many times over. This low restriction air filter allows the engine to breathe more freely, which means a better throttle response as well as more power throughout the rev range. All K&N factory replacement filters are 50-state legal.

Retains OE airbox and replaces OE air filter. Filters are shipped pre-oiled. To clean the filter, purchase the K&N recharger kit #99.5000.
