Flat foam sealing ring provides a secure seat against the airbox, even in the worst riding conditions
Twin Air filters are slightly smaller than stock, making them easier to change while increasing dead air space around the filter for better performance
Backfire filters include a laminated layer of backfire-retardant foam
