Two Stage Competition Air Filter - 156145

particles, yet allows more airflow than regular two- separate-layer filters (flow bench tested) Flat foam sealing ring maintains a secure seal to the airbox, even in the worst riding conditions Two Air filters run slightly smalled than stock, making them easier to change and increasing the dead air space around the filter for better performance.
