HKS Super SQV (Sequential Blow Off Valve) uses an amazing sequential valve structure and a differential pressure control system, which allows for a wide operating range from low boost to high boost. Its Pull-Type relief design ensures stable operation regardless of the amount of boost pressure. The Super SQV will support new generations of turbocharged vehicles.
Pull-Type blow-off valves will work for any turbocharged vehicle, from stock to highly tuned. Typical push-type blow-off valves require spring load settings for each vehicle specification. If the spring load setting is too low, the valve may leak under a high boost and the desired boost setting may not be reached. If the spring load setting is too strong, it may not open at a low boost. The Super SQV will operate under any boost pressure setting without leaking
