HKS 71008-AN024 Super Sequential Blow Off Valve 4 Kit SSQV4 Nissan S13

In 1994, HKS introduced the first Sequential Blow-Off Valve  featuring a unique, pull-type, sequential valve structure and a differential pressure control system.  This advanced pull-type relief system allowed for stable operating ranges from low to high boost pressures.  Since imitation is the highest form of flattery, HKS has once again redesigned the physical aspects of the Super Sequential Blow Off Valve to thwart off the counterfeiters.

The reliable functionality of the Super SQV 4 is unchanged and utilizes the same mounting flanges as all previous generation SSQVs.  This assures compatibility with all optional HKS SSQV inserts, recirculation fittings and recirculation kits.

Super SQV 4 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 finish off the re-design of this blow-off valve with style, HKS stamped a holographic like version of their logo which only accentuates the bov even more.
