Blow Off Valves
HKS blow off valves for turbocharged engines, designed to manage excess charge-air pressure during throttle lift and deliver the distinctive sound associated with the Super SQV range.
HKS Blow Off Technology — Pressure Control and Signature Sound
When the throttle closes on a turbocharged engine, pressurized intake air may need to be discharged or recirculated according to the vehicle's system design. HKS develops blow off valves to manage this pressure under appropriate operating conditions.
HKS Super SQV employs a sequential valve structure and differential-pressure operation to accommodate a range of operating conditions. Its fin design also contributes to a distinctive discharge sound, although the actual sound varies with the installation and associated components.
Check whether a vehicle-specific or universal kit is required, and verify atmospheric discharge or recirculation requirements and applicable regulations before installation.
