Backfire Air Filter

• 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
• Air filter cages available separately for some models
