HKS Super SQV 4+RETURN KIT CZ4A

This HKS Super SQV 4+RETURN KIT includes the Super Sequential Blow-Off Valve (SQV) and a dedicated return kit specifically designed for the CZ4A chassis. The SQV is a popular choice for turbocharged vehicles, and this kit provides everything needed to install it, including the necessary plumbing and fittings for a complete setup. It's designed to release excess boost pressure from the turbo system when you lift off the throttle, preventing compressor surge and helping to maintain the turbocharger's efficiency.

The Super SQV 4 features a unique, patented, pull-type blow-off valve structure that ensures a stable seal even under high boost conditions. This advanced design helps prevent boost leaks, which can rob your engine of power and reduce turbo response. The dual spring system also allows for fine-tuning of the valve's operation, accommodating a wide range of boost pressures. The included return kit ensures that the vented air is routed back into the intake system, which is often required for emissions compliance and can help maintain smoother idling and prevent fuel mixture issues.

When installing this kit, it's important to note that it is not CARB approved and cannot be shipped to California. This is a well-built component from HKS, a well-known name in the performance aftermarket, and it's designed to integrate cleanly with the CZ4A's factory turbo plumbing. Proper installation is key to achieving the intended performance benefits and ensuring the longevity of your turbo system.
