TiAL QR blow-off valve fitted with a 12 PSI spring, a 29mm inlet and a black finish. It provides controlled venting of excess boost pressure for forced-induction engines while maintaining a positive seal under boost. The compact QR design suits tight piping runs and the 12 PSI spring determines the valve’s cracking pressure, offering predictable and repeatable venting behavior during throttle changes.
