Description
Coarse open-pore foam catches airborn dirt, grime and sand. Fine open-pore inner foam acts as second filter to trap the smallest particles while ensuring maximum air passage. Adhesive withstands repeated cleaning. Smaller than stock to increase air space and circulation around filter.
- Dual-bonded foam design filters out even the smallest dirt particles, while allowing more airflow than two separate layer filters (flow bench proven)
- 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
- Flat foam sealing ring securely seats against the airbox, even in the worst riding conditions
