The TiAL Sport QR blow-off valve with a 2 psi spring and 1.5-inch inlet in black is a compact recirculating-style valve tuned to open at about 2 psi. Built for charged-intake systems with 1.5-inch plumbing, it vents excess boost back into the intake or atmosphere depending on plumbing, and the black finish keeps the valve visually discreet while providing a serviceable replacement option.
