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

Description

The Twin Air Flame-Retardant Pre-Oiled Backfire Filter is a high-performance, dual-layer offroad air filter designed specifically for Yamaha YZ and WR four-stroke dirt bikes with Twin Air Airbox Kits (sold separately). This filter is pre-oiled with Twin Air BIO Foam Filter Oil, ensuring even coverage and optimal filtration. The coarse, open-pore outer foam traps dirt, sand, and grime, while the fine inner foam captures the smallest particles. Its backfire-resistant design eliminates the restrictive stock backfire screen, allowing maximum airflow and protection. The greaseless sealing ring ensures a tight, breathable fit, and the washable, reusable construction means you can use the filter up to 40-50 times. Assembled by hand and inspected for a perfect fit, this filter boosts performance with biodegradable oil that is safe to wash down the drain. Packaged in a resealable bag for convenience.
