The TiALSport QRJ blow-off valve with a 3 psi spring offers low-crack boost relief for turbo systems; flanges are not included. Finished in purple, it provides the same controlled venting to reduce compressor surge and smooth throttle transition. This compact valve is intended for installations that require a light spring setting while sourcing their own flange hardware.
