HKS Racing SQV Dump Valve Kit Specification

AUTHENTICITY GUARANTEED! DriftShop is an official distributor of HKS Europe. Our HKS products are 100% authentic!

HKS Super Racing SQV (for SeQuential Blow Off Valve) is the current benchmark in the market, either in terms of performance, endurance or quality/price ratio.

HKS original 3-chamber structure ensures the stable operation of blow-off valve regardless of the amount of pressure. Large 51mm valve performs great with high power and large displacement engines. Adjustable pre-load allows a wide range of application.

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 reliefless 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.

This kit is universal, requiring adaptation to your specific application.
