The HKS Sequential Blow-Off Valve has been one of the favorite modifications among sport compact drivers for more than 20 years. From its unique chirping sound, to the ability to outperform OEM units this a blow off valve one can depend on.
The latest HKS Super SQV4 Blow Off Valve employs the same design qualities as the original which involves a pull-type sequential valve structure with a differential pressure control system. This design allows for stable operating ranges from low, to high boost pressures.
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 reach. If the spring load setting is too strong, it may not open at low boost. The Super SQV will operate under any boost pressure setting without leaking.
Dual Valve Structure, Sequential System
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.
- Super SQV4 Kit to replace the factory air bypass valve.
- Three-spoke fins are included in the kit, which allows the valve to release the compressed air and create unique and sharp high frequency sound.
- Connecting to the stock air bypass hose recirculates to the suction.
