HKS Super SQV (Super Sequential Blow Off Valve) uses a unique sequential valve structure and a differential pressure control system, which allows for a broad operation range from low boost to high boost.

The HKS SSQV silver triple-fin discharge design produces a powerful and unique aggressive blow-off sound along with added visual distinction. Additional triple-fin inserts are available in gold (standard high frequency sound) for visual appeal and in purple metallic (emits a lower frequency sound than both the standard and gold SSBV inserts) for an alternate sound and appearance. SSQV inserts are easily interchangeable within minutes.

HKS SSQV Re-Circulation Fitting inserts enable the SSQV to reroute discharged compressed air back into the intake stream to create a closed loop system to prevent bogging / stumbling of rich air/fuel ratio conditions in mass-air sensor equipped vehicles.
