Replacement TwinAir Filter for Power Flow Kit. Dual-stage foam filters are used by factory race teams and leading riders worldwide. The dual-bonded foam design removes even microscopic dirt particles while allowing more airflow than regular two separate layer filters. The flat foam sealing ring maintains a secure seal to the airbox, even in the worst riding conditions. Twin Air filters run slightly smaller than stock, making them easier to change and increasing the dead air space around the filter for better performance. Part No. 15-4211.T.
