Description
HKS Super Sequential Blow-Off Valve (SSQV4)
Product Overview: HKS Super Sequential Blow-Off Valve (SSQV4) 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.
Vehicle Application: 2023-2026 Honda Civic Type R (FL5)
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: Features: Quickly relieves excess boost pressure that is no longer needed by the turbocharger and reduces the load on it. (When throttle is off) While operating at low boost pressure, it does not relieve at high boost range and maintains the set boost pressure stably. Installed it in a visible space in the engine bay, it significantly improves the overall aesthetic of the engine bay. A suction return hose is included in the kit, making it applicable to safety standards. When venting to atmosphere, the SUPER SQV4's distinctive high-frequency, crisp operating sound makes its presence very noticeable.
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.
