Description

Details

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.

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.

  1. Awesome

    By Emilio December 20, 2017

    Awesome product by HKS. Easy bolt on install and comes with extra hose length/ zip ties if needed. Looks good under the hood and sounds great.

  2. HKS BOV

    By Robert October 30, 2017

    Decided to go with the HKS cause I love the sound but part DOES NOT come with the recirculated hose as shown in one of the product pictures so you can not run this on stock you will need a tune. I ran the hks on stock psi for a couple of days an plugged my bypass with the part provided and gave little to no atmosphere release and car was running rough and was forced to return to stock until tune. Overall I'd rate this 8 - 10 because it did not come with the recirculating hose to run on stock tune and didn't live up to atmosphere sound of previous HKS BOV's
