TWIN AIR BACKFIRE FILTER KX450 2019 TWIN AIR

Dual-bonded foam design filters out even the smallest dirt particles, while allowing more airflow than two separate layer filters (flow bench proven)

Flat foam sealing ring securely seats against the airbox, even in the worst riding conditions

Twin Air filters are slightly smaller than stock to make them easier to change and to increase dead air space around the filter for better performance
