A vehicle specific Super SQV IV package for the B58, supplied with the adapters and hardware needed to bolt onto the factory charge piping. The valve runs a sequential dual valve arrangement under differential pressure control, with a small primary valve that opens instantly on throttle lift and a larger secondary valve that the primary then pulls open once the pressure difference across the chambers peaks. The pull type relief design seals harder as boost rises, so unlike a push type valve it needs no spring load tuning to suit a given boost target. The body is silver coated aluminium die cast, the secondary valve is die cast metal, and a triple fin funnel sets the release note. A circulation adapter is included, allowing a recirculating setup if return piping is fabricated.
