What is the main benefit of the HKS SSQV IV valve over the stock bypass valve?

The HKS SSQV IV uses a unique diaphragm management system that allows it to open and close much faster than the factory bypass valve. This results in improved boost response and a more distinct sound when releasing boost.

Why is a return kit included, and is it necessary?

The return kit recirculates the vented air back into the intake system before the turbocharger. This is important for modern turbocharged cars to help maintain accurate air-fuel ratios and prevent potential check engine lights that can arise from venting all air to the atmosphere.

Can this kit be installed on any GR Supra, or does it require other modifications?

This specific kit is designed for the GR Supra (DB42/DB02) and requires the use of an HKS R/S intake system. It is not a universal fit and may not be compatible with other intake or turbocharger setups.

Product Details

If you're looking to upgrade the blow-off valve system on your GR Supra (DB42/DB02) and are running an HKS R/S intake, this HKS SSQV IV + Return Kit is a solid choice. This kit replaces the factory bypass valve with a more responsive HKS Super Sequential Blow-Off Valve (SSQV) and includes the necessary components to recirculate the vented air back into the intake system. This helps maintain proper air-fuel ratios and prevents potential check engine lights that can occur with vent-to-atmosphere setups on modern turbocharged vehicles.

The SSQV IV is well-known for its rapid response and ability to handle higher boost pressures than stock. It uses a unique diaphragm management system that ensures it opens and closes quickly, providing a crisp sound and excellent boost control. The included return kit is specifically designed to integrate seamlessly with the HKS R/S intake, making installation more straightforward. This setup is ideal for tuners and enthusiasts who want precise control over their boost and a distinct sound signature.

This kit is designed for use with the HKS R/S intake system on the GR Supra. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for detailed guidance on fitting this component to your vehicle.
