Description
Air filter performance directly impacts throttle response, fuel efficiency, and engine longevity—especially in dusty riding conditions where stock filters restrict airflow and trap contaminants. The Twin Air Pre-Oiled Air Filter delivers superior filtration through its dual-layer foam construction while maintaining the unrestricted airflow your CRF demands. Pre-oiled and ready to install, this filter eliminates guesswork and keeps your engine protected from the first ride.
