Show original supplier description
The HKS Super SQV4 (Silver) Blow-Off Valve Kit is engineered as a direct replacement for the stock air bypass valve on the Nissan R35 GT-R. These fins allow the valve to release compressed air with a distinct and sharp high-frequency sound, providing an audible confirmation of boost release. The installation process is straightforward, as the Super SQV4 kit utilizes the factory air bypass hose for recirculation back to the suction side. This ensures that the engine's air-fuel mixture remains unaffected while still delivering the characteristic blow-off valve sound. The kit includes two SQV4 valves, installation hardware, and instructions, making it a comprehensive solution for enhancing the performance and sound of your GT-R's induction system. Fitment is specifically for the 2009+ Nissan R35 GT-R equipped with the VR38DETT engine. It is important to note that this product is not CARB Legal and cannot be sold or shipped to California.
