What is the primary function of the HKS SUPER SQV 4?

The HKS SUPER SQV 4 is a blow-off valve that releases excess boost pressure from the intake system when the throttle is closed. This helps protect the turbocharger from damage caused by compressor surge and can lead to improved throttle response.

What makes the SUPER SQV 4 different from other blow-off valves?

The SUPER SQV 4 utilizes a unique sequential valve structure and a dual spring system. This advanced design allows it to effectively manage boost pressure across a wide range, from low to high boost, ensuring a proper seal under boost and a quick release when needed.

Does this blow-off valve come with all necessary installation hardware?

The HKS SUPER SQV 4 kit includes the blow-off valve unit itself. While it is designed to integrate with factory or aftermarket piping, it's recommended to refer to the manufacturer's installation guide for details on vacuum hose connections and any additional hardware that may be required for your specific setup.

Product Details

This kit includes the HKS SUPER SQV (Super Sequential Valve) 4 blow-off valve specifically designed for the Nissan GT-R BNR34 and BCNR33 models equipped with the RB26DETT engine. The SUPER SQV 4 is an updated version of HKS's popular blow-off valve, featuring a unique, finely-tuned sequential valve structure and a dual spring system. This design ensures that the valve operates effectively across a wide range of boost pressures, from low boost to high boost, preventing both compressor surge and boost leaks.

The SUPER SQV 4 is constructed from well-built aluminum and features a striking visual appeal with its polished finish. Its advanced sequential valve mechanism allows for a rapid and complete discharge of excess boost pressure when the throttle is closed, which helps protect your turbocharger from damage and can lead to improved throttle response. The dual spring system is a notable feature, providing the necessary tension to keep the valve sealed under boost while still allowing it to open smoothly and quickly when needed. This makes it a solid option for enthusiasts looking to manage boost pressure effectively on their RB26DETT engine.

Installation involves connecting the blow-off valve to the factory or aftermarket intercooler piping. While the SUPER SQV 4 is designed as a direct replacement for the stock unit, it's always recommended to consult the manufacturer's installation instructions for specific details regarding vacuum hose connections and mounting. Please note that this part is not CARB approved and cannot be shipped to California.
