Blow Off Valve Kit / AC 9000/Yamaha Sidewinder 998cc Turbo

This blow off valve fits easily into your stock charge tube to deliver that classic turbo sound. This also eliminates the factory diverter valve which is plastic. Plastic diverter valves are known to warp and fail, especially under high boost pressures. This kit includes a BMP blow off valve, and a BMP plug for your intake tube.
