Product Overview: HKS SSQV4 Blow Off Valve Return Kit Plus - 21+ Toyota GR Yaris / 23+ GR Corolla 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: Features: - HKS changed the intercooler charge pipe for the outlet side to the casting aluminum-made pipe compared to the resin-made stock ones. This prevents expansion or damage to the pipe due to age deterioration. - Coordinate your engine bay stylishly with the presence of the SQV IV at the front of the engine. - Using the provided suction return hose meets the automobile inspection in Japan. - The kit allows using the combination use of the stock air bypass valve without any cancellation when installing the SQV IV. - Body color: Silver, Includes Suction Return kit.
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.
