HKS Racing SQV Universal BOV

The HKS Racing Sequential Blow Off Valve Assembly (71008-AK004) features an original 3-chamber structure for stable operation regardless of pressure. It incorporates a large 51mm valve, ideal for high-power and large-displacement engines. The adjustable pre-load allows for a wide range of applications. This relief-less valve system ensures stable operation at all boost levels, minimizing valve stick and achieving high durability (tested over 1 million operations). An installation flange is included, which requires welding to a pipe; a piping hose is not included. The flange size differs from existing SSQV models.
