The TiAL Sport QR blow-off valve with a 6 psi spring and 1.5-inch inlet in black is a higher-opening recirculating valve that vents excess boost at about 6 psi. Suited to systems with 1.5-inch plumbing, the firmer spring raises actuation for higher boost thresholds and the black finish keeps the valve visually low-profile while serving as a direct replacement for matching plumbing sizes.
