Twin Air Flame-Retardant Pre-Oiled Backfire Filter For Yamaha YZ/WR

Description

The Twin Air Flame-Retardant Pre-Oiled Backfire Filter is designed specifically for Yamaha YZ/WR four-stroke dirt bikes equipped with Twin Air Airbox Kits (sold separately). Pre-oiled with Twin Air BIO Foam Filter Oil, this filter utilizes advanced oiling machines for consistent pore coverage and superior filtration. Its fused, dual-layer backfire-resistant foam construction eliminates the need for restrictive stock backfire screens, while the coarse outer foam traps larger debris and the fine inner foam captures even the smallest particles. A thick, flat foam greaseless sealing ring ensures a perfect airbox seal and improved airflow. Built to withstand repeated washings, this washable and reusable filter can typically be used 40-50 times, making it a cost-effective choice. The high-quality, hand-assembled construction and even cell pore distribution result in reliable performance and fit. Packaged in a resealable bag for convenience.
