About this part

Product Details

This is the HKS SUPER SQV4 Suction Return Kit, designed for the FL5 model. It's a well-built kit that helps your turbocharger respond more quickly. The SUPER SQV4 uses a unique, pressure-balanced, asymmetrical valve structure, which means it can open and close smoothly even under high boost conditions. This design helps prevent both boost leaks and compressor surge, contributing to a more efficient and responsive turbo system.

The kit includes everything needed for installation, making it a straightforward upgrade for your turbo system. By recirculating the excess boost pressure back into the intake system, it helps maintain smoother operation and can reduce the stress on your turbocharger. This can lead to improved overall performance and a more consistent power delivery from your turbo.
