TiAL QR blow-off valve fitted with a 12 PSI spring, a 1.0in inlet and a purple finish. This valve vents excess boost pressure for forced-induction engines while maintaining a positive seal at lower pressures. The QR body is compact for tight installations and the 12 PSI spring establishes the opening threshold, delivering consistent venting behavior under throttle lift or spool conditions.
