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. This Super SQV maximizes the charge-response that repeats pressure-charging and pressurized air relief by throttle on and off and supports new generations of turbocharged vehicles.




Overwhelming Low Exhaust Pressure - 50% of Original Pressure φ75 large diameter pipe and full straight structure reduce the exhaust pressure to 50% of the stock. This significant exhaust pressure reduction enables the turbine to run smoothly from low RPM range, which results in the engine output increase in an entire speed range. Also, this pressure reduction effect is enhanced as the tuning level becomes more advanced; the engine output can be increased to 540ps without engine power-loss.
