The TiAL Sport QR blow-off valve with a 6 psi spring and 1.5-inch inlet in silver provides higher-pressure actuation near 6 psi for 1.5-inch charged-intake plumbing. Built to vent excess boost at a firmer threshold, it suits applications needing a stronger spring rate and offers a neutral silver finish for a clean, understated appearance while serving as a direct replacement option.
