Twin Air Backfire Repl. Filter KTM 154217

Filter only for use with Twin Air Power Flow kits

Twin Air dual-stage filters are the choice of top factory teams and riders worldwide

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 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
