Description
HKS Racing SQV Blow Off Valve - Universal
Product Overview: HKS Racing SQV Blow Off Valve - Universal is a forced-induction pressure-control component designed to manage excess charge pressure when the throttle closes. This listing is structured around the exact HKS product/SKU so shoppers can match the component to the intended vehicle or build without relying on a generic product-family description.
Driver Benefit: Proper pressure relief can improve transient behavior and help protect the compressor from repeated surge events during shifts and throttle lift.
Recommended Use: Best suited to turbocharged performance applications where the charge system is being upgraded or tuned for higher boost and sharper response.
Technical & Fitment Notes
- Use the HKS part number/SKU as the primary reference when confirming exact configuration and installation requirements.
- Professional installation is recommended when the component affects engine operation, suspension geometry, braking, fuel delivery, or other safety-critical systems.
- Original catalog note: 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.

Fitment and specifications can vary by HKS part number, model year, trim, transmission, drivetrain, and market. Confirm the SKU and application before ordering, particularly on modified vehicles.
