Product Description
Keep your Yamaha ATV running at peak performance with the Wide Open AF3240W Two-Stage Competition Air Filter. Using two layers of high-performance foam, it traps both large and fine particles — dust, dirt, and mud — before they ever reach your cylinder. It drops right into the stock airbox with no modifications, flows better than OEM, and can be cleaned and reused indefinitely.
