Features & Product Details

The HKS SSQV Blow Off Valve is one of the most unique and sought after valve on the market. Its unique pull type sequential valve design gives a complete seal under low boost and seals tighter under high boost making it one of the most reliable valves on the market. Due to its design it gives you a very distinct sound and is arguably the best sounding valve available. Reliability is key when it comes to blow off valves and the SSQV will give you years of worry free performance while improving the lifespan and reliability of the turbo as well.

The SSQV4 is improved over the previous generations, however you can use the inserts, adapters and recirculation kits from the previous generation of valves.

      A:  This Blow Off Valve will work well for a 2017 STI. This one in particular is strictly an Atmospheric Blow Off Valve.
