HKS SSQV IV + Return Kit GR SUPRA (DB42/DB02) for Normal Box

This HKS SSQV IV Blow Off Valve and Return Kit is specifically for the GR Supra (DB42/DB02) models equipped with the normal air intake box. You'll receive the SSQV IV blow-off valve itself, along with the necessary return piping and hardware to integrate it into your Supra's factory setup. This kit is designed to replace the stock bypass valve, offering a more distinct sound and improved response when the throttle is released.

The SSQV IV is a well-known component in the performance tuning world, recognized for its reliable operation and distinctive sound. It uses a unique diaphragm and spring-loaded system that ensures it opens and closes effectively, even under high boost conditions. The included return piping is crucial for maintaining proper air-fuel ratios by recirculating the vented boost pressure back into the intake system, preventing check engine lights and ensuring smooth operation. This setup is particularly beneficial for turbocharged vehicles like the GR Supra, where managing boost pressure efficiently is key to performance and engine health.

When installing this kit, you'll be working with the factory air intake box. The design of this kit aims for a direct fit within that configuration, simplifying the installation process compared to universal blow-off valve setups. It's important to note that this product is not CARB approved and cannot be shipped to California. For those outside of California, this kit offers a way to enhance the auditory feedback of your turbocharged Supra and potentially see improved throttle response after gear changes.
