HKS SSQV4 Blow Off Valve
Product Overview: HKS SSQV4 Blow Off Valve 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: 2020-2026 Toyota GR Supra 3.0L B58 (A90)
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 - This is a product unique to HKS that enables the installation of blow-off valves in valvetronic engines that do not generate negative intake manifold pressure. - When released to the atmosphere, the high frequency and sharp operating sound peculiar to SUPER SQV IV greatly appeals its existence. - By changing the genuine resin charge pipe part to an aluminum pipe, durability has been improved and ventilation resistance has been reduced (see the figure below). Includes: - Blow off Valve - Aluminum Charge Pipe for SSQV4 Blow Off Valve
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.
