Product Description
The HKS Super SQV IV Blow Off Valve Kit is the latest iteration on the extremely successful HKS Super Sequential Blow-Off Valves. This particular kit includes the parts to make it a bolt on system that adds much needed engine bay flare, plus it includes all the piping to keep the OEM recirculated by pass valve. It features the latest technology to provide reliable and consistent performance for the WRX's FA20 turbo.

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 manage more power in an atmospheric or recirculated system, while added that much coveted blow off turbo woosh (when atmospheric). This kit was designed specifically for the FA20 and a viable solution for stock to high power setups.
