HKS Super SQV 4+RETURN KIT ER34/ECR33

This HKS Super SQV 4+RETURN KIT includes the Super SQV 4 blow off valve and a dedicated return pipe, designed for specific Nissan ER34 and ECR33 chassis. The Super Sequential Valve (SSV) technology is HKS's well-known design that helps manage boost pressure by releasing excess air when the throttle closes. This helps prevent compressor surge and can improve throttle response.

The Super SQV 4 features a unique, high-flow diaphragm and a dual spring structure. This setup allows for a strong seal against boost pressure while still opening smoothly. The included return pipe is designed to recirculate the vented air back into the intake system, which is often required or preferred for certain vehicle setups and emissions compliance. This particular kit is for specific Nissan models, ensuring a more direct installation compared to universal kits.

Please note that this kit is not CARB approved and cannot be shipped to California. Always refer to manufacturer documentation for the most accurate installation details and compatibility information for your specific vehicle.
