HKS Racing SQV Universal BOV

The HKS Racing SQV is the newest in the line of SQV Blow Off Valves offered by HKS. It utilizes HKS’s original 3-chamber structure, ensuring stable operation of the blow-off valve regardless of the amount of pressure. Large 51mm valve performs great with high power and large displacement engines while adjustable pre-load allows a wide range of application.

3-Chamber System: Typical blow off valves require spring load settings for each vehicle specification. If the spring load setting is too low, the boost pressure may be relieved under high boost, and the desired boost setting may not be reached. If the spring load setting is too strong, the valve may not open at low boost. HKS RACING SQV utilizes a relief less type; therefore, it delivers stable operation at all boost levels.

Durability tests of over 1 million operations minimizes the chances of valve stick and achieves high durability.

Product Features:

  •  51 MM large capacity valve.
  •  3 Chamber structure & relief less valve.

  •  Weld on installation flange is included. Flange size is different from current SSQV.
