- Top factory teams and riders around the world choose Twin Air dual-stage air filters
- 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
