HKS SUPER SQV 4 GT-R R35 VR38DETT (REPLACE)

If you're looking to fine-tune the boost control on your Nissan GT-R R35 with the VR38DETT engine, the HKS SUPER SQV 4 blow-off valve is a solid option. This unit is designed to replace the factory blow-off valve, helping to manage excess turbocharger pressure when you lift off the throttle. By venting this pressure, it helps protect your turbo from damage and can contribute to a more responsive feel when you get back on the gas.

The SUPER SQV 4 features a unique, pull-type relief valve structure that ensures it can handle high boost pressures without leaking. Its construction uses die-cast aluminum for the main body, making it lightweight yet strong. The valve itself is made from machined aluminum, and the internal diaphragm is made of a heat-resistant silicone rubber. This combination of materials is chosen for durability and consistent performance under demanding conditions. The kit includes all the necessary components for installation, designed to integrate with the factory plumbing for a straightforward swap. You'll notice a distinct, high-pitched sound when the valve actuates, which is a signature of the SUPER SQV line.

This blow-off valve is a direct replacement for the stock unit, meaning it's built to fit right into the existing setup on your GT-R R35. While it's designed for performance, 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 the most accurate guidance on fitting this component to your vehicle.
