Product Description

The Twin Air 160078 Airbox Cover allows off-road riders and mechanics to thoroughly pressure wash the inside of the airbox without risking water entering the engine intake tract. Custom designed for Yamaha YZ and WR models, this heavy-duty wash cap creates a complete watertight barrier directly over the carburetor or throttle body intake boot.

Manufactured from high-strength PVC with a durable rubber sealing ring, this airbox cover ensures leak-free protection against high-pressure spray, mud, and harsh cleaning chemicals. The kit comes complete with a dedicated top screw, allowing quick and secure installation once the dirty air filter is removed.
