The HKS Super SQV IV By-Pass Valve is the latest iteration on the extremely successful HKS Super Sequential Blow-Off Valves. This particular kit includes the parts to make it a recirculated system. It features the latest technology to provide reliable and consistent performance for forced induction applications.

The SSQV IV is made out of Die Cast Aluminum and features a dual valve design which allows for quick response yet still handles high boost applications. And like most know, the HKS system has a distinct look and sound which sets it apart from the competition.

This kit is ideal for drivers looking to not throw off too much by going to an atmospheric system, the recirculated system makes it easier to tune with bolt-ons. It also works as an atmospheric BOV if you decided to later go that route.
