Tork Motorsports is happy to bring affordable and great sounding blow off valves to you while not cutting corners on quality! These blow off valves are made from 6061 Billet Aluminum, anodized black, adjustable, direct OEM replacement, and a very easy install! These blow off valves will also allow you to hold a higher boost pressure, have a most crisp bov sound, and they look much better the the OEM plastic diverter valves!.
