- 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.
- Slightly smaller than stock, making them easier to change while increasing dead air space around the filter for better performance.
For many years, Twin Air Factory Pre-Oiled filters were only available to our top professional race teams and OEM customers. The results were so good that in 2005 we made them available to everyone.
The same features as the Original filter, with the added convenience of wash-down-the-drain cleaning. A Dual-Stage Air Filter is submerged in BIO Liquid Power Filter Oil, massaged to ensure all pores are evenly coated, and placed in a temperature-controlled room to allow the oil to completely cure. You just open the resealable bag and install.
