TiAL QR blow-off valve fitted with a 12 PSI spring, a 1.5in inlet and a red finish. It relieves excess boost pressure in forced-induction engines while maintaining a positive seal under boost, aiding compressor protection and throttle transitions. The 1.5in port accommodates higher-flow plumbing and the 12 PSI spring sets the valve’s opening point for reliable venting behavior.
