HKS Super SQV (Sequential Blow Off Valve) uses a unique sequential valve structure and a differential pressure control system, which allows for a broad operating range from low boost to high boost. Its Pull-Type relief design ensures stable operation regardless of the amount of boost pressure.

The HKS SQ4 blow off valve comes with a silver-coated aluminum die-cast body which combines the ultimate in looks and durability in the engine compartment. The secondary valve main portion is made of die cast metal. The triple fins set at the center of the funnel produces a dynamic and aggressive sound. The Pull-Type valve operation offers more precise relief of excess boost and is compatible for a wider range of boost pressure compared to typical push-type blow off valves. Lift off the throttle, and the primary valve instantly opens, quickly discharging initial excess boost pressure. This valve combined with the Primary Valve from the sequential dual valve structure. Optimal blow-off operation from how to high boost ranges without leaking. At low boost ranges the Primary Valve opens, and at high boost ranges the Secondary Valve also opens, resulting in linear response and optimal blow-off operation at all boost levels.
