TiAL Sport QR Recirculating Blow-Off Valve - 34mm Discharge, 10 PSI Spring - Black

The TiAL Sport QR is the recirculating version of the Q blow-off valve, routing vented air back into the intake through a 34mm discharge tube so it works cleanly on mass-airflow engines. It has a 51mm valve, all billet aluminum construction with a black anodized cap, a Nomex-reinforced silicone diaphragm and an M10 vacuum port, and ships with the 10 PSI spring installed. The QR bolts to any standard TiAL BOV flange without welding and shares its lower body with the Q for a vent-to-atmosphere conversion.
