The HKS unit is by far the most popular BOV on the market due to HKS`s detail to quality, design and distinctive sound.

This is what HKS has to say about their updated Super SQV III design:

In 1994, HKS introduced the first Sequential Blow-Off Valve that blazed the auto industry with a unique pull-type sequential valve structure and a differential pressure control system. This advanced system allowed for a broad operation range from low to high boost.

The HKS Super Sequential Blowoff Valve (SSQV) is a dual stage pull type relief valve. This pull-type relief design ensures stable operation regardless of boost pressure. Unlike other blow off valves that are push type, the SSQV will not leak under high boost conditions nor under vacuum at idle. Being of a pull type valve structure, the SSQV can not physically leak under any level of boost because boost pressure also keeps the valve closed against its seat. The SSQV is actuated by pressure alterations only, not by the rate of pressure or vacuum in the line, which ensures a quick valve response and complete closure during idle.

On typical blow-off valve designs, a large valve is utilized in order to accommodate high boost / high horsepower applications. However, these large valves tend to react slowly and require high activation pressure to open, therefore are not able to activate and prevent compressor surge at light-load conditions. On the other hand, smaller, fast reacting valves do not discharge the airflow capacity required for high horsepower applications and tend to creep open and leak as the boost pressure overpowers the spring on these push type valves. For maximum performance, the HKS SSQV incorporates both a small primary valve for ultra quick activation, along with a larger secondary valve for additional discharge capacity. The SSQV is engineered to initially open the small primary valve at light throttle and load conditions, then sequentially opens the secondary valve for additional relief capacity under high boost and load conditions.

The Super SQV III features include a nickel-plated, die-cast metal secondary valve, which is swaged to the primary valve, a stainless steel C-Clip and spring to increase sealing and durability. To assure buyers that they are purchasing an authentic HKS product, the new design incorporates a holographic HKS logo on the back of the valve, as well as additional HKS logos cast onto the body structure.

The Super SQV III utilizes the same mounting flanges as all previous generation SSQV's to assure compatibility with all optional HKS SSQV inserts, recirculation fittings and recirculation kits.
