This is a PULSAR PSR Next Gen 50mm blow-off valve (BOV) with a 52mm valve diameter, designed to vent excess charge pressure from the intake piping during throttle lift-off. It uses a spring pressure of 10.5 psi at manifold vacuum for reliable sealing and response, and the kit includes the valve body, an inlet V-band connection, and an aluminum weld-on flange for mounting to custom charge piping.

Fitment: Universal, for charge piping on any turbocharged engine.
