Twin Air Foam Air Filter - 153909C
Twin-Air dual-stage filters are used by factory race teams and leading riders around the world Dual-bonded foam design removes even microscopic dirt particles, yet allows more air flow than regular two separate layer filters (flow bench tested)

Flat foam sealing ring maintains a secure seal to the airbox, even in the worst riding conditions Twin Air filters run slightly smaller than stock, making them easier to change and increasing the dead air space around the filter for better performance.
