THE RACE PLUG FUEL PRESSURE RELIEF VALVE with VITON O-RING
Replaces the stock or shimmed pressure relief valve. Removing the stock pressure Relief valve will help maintain fuel rail pressure during full throttle driving by completely blocking the pressure relief port. It also helps eliminate low fuel rail pressure DTC codes (P0087 and P1011) that are caused by insufficient PRV spring pressure.
