The TiALSport QR blow-off valve in black includes a 2 psi spring and is sized at 34mm for compact turbo installations. It provides low crank pressure release to help prevent compressor surge and calm boost fluctuations on throttle lift. The small footprint and light spring make it appropriate for charge piping routes where space is limited and a gentle venting action is preferred.
