The HKS SUPER SQV (Sequential Blow-Off Valve) features an advanced two-stage sequential valve structure, utilizing both a primary and secondary valve to provide precise pressure control across a broad operating range, from low to high boost. Its differential pressure control system ensures smooth, responsive performance. Unlike typical blow-off valves, the HKS SQV incorporates a unique "relief-less operation method," which minimizes pressure relief during high boost conditions. This design optimizes charge response, especially during repeated throttle ON/OFF cycles, delivering superior performance and maintaining consistent boost pressure.

Applications

• FAIRLADY Z (2022)

Features

• Blow-off valves are installed on the left and right banks of the VR30DDTT engine to quickly release unnecessary boost pressure from the left and right turbochargers, reducing the burden on the turbochargers (when the throttle is off).
• The hose between the turbocharger and intercooler is changed to a special 4-ply silicone hose and the SQV4 is installed.This also strengthens the hose section.
• All parts other than the SQV4 main unit are black in color, making the SQV4 main unit stand out.
• The return hose is a specially molded silicone hose, designed to fit snugly in the engine bay.
