The cast aluminum back plate includes built-in internal breathers. Also, a bolted-in dyno tuned velocity stack decreases the restriction of air into the throttle body. The result is more power you can feel with outstanding engine protection.
Spacers and hardware are included to mount your stock Harley Davidson air cleaner cover and a bump-seal is used at the base to provide a perfect seal. Installation can be performed in 90 minutes or less.
The RK-3931 is covered by the famous K&N Million Mile Limited Warranty.
