The HKS SSQV4 Blow Off Valve Return Kit Plus is a high-performance sequential blow-off valve designed for Nissan 400Z RZ34 models from 2023 onward. Featuring an advanced two-stage valve structure, it utilizes both a primary and secondary valve to deliver precise pressure control across a wide boost range. The differential pressure control system ensures smooth and responsive operation, enhancing throttle response and overall turbo performance. Its relief-less operation minimizes pressure relief during high boost conditions, reducing compressor surge and maintaining consistent boost levels. Constructed with durable materials and engineered for reliability, this BOV offers improved sound and performance characteristics, making it suitable for enthusiasts seeking a high-quality upgrade.

This kit is specifically designed for 2023+ Nissan 400Z RZ34 models, providing a direct bolt-on replacement for the factory valve. It is intended for use in street and track applications where precise boost control and responsiveness are desired. The return kit includes all necessary components for installation, ensuring compatibility with the vehicle’s existing turbo system. Suitable for tuning and performance upgrades, this blow-off valve enhances the vehicle’s boost stability and sound profile. Proper installation requires basic mechanical skills, and it is recommended for use with vehicles equipped with a turbocharged engine seeking improved pressure regulation and a sporty sound.

Overview

The HKS SUPER SQV (Sequential Blow-Off Valve) features an advanced two-stage sequential valve structure, utilizing both a primary and secondary valve to provide precise pressure control across a broad operating range, from low to high boost. Its differential pressure control system ensures smooth, responsive performance. Unlike typical blow-off valves, the HKS SQV incorporates a unique "relief-less operation method," which minimizes pressure relief during high boost conditions. This design optimizes charge response, especially during repeated throttle ON/OFF cycles, delivering superior performance and maintaining consistent boost pressure.

Applications
  • FAIRLADY Z (2022)
Features
  • Blow-off valves are installed on the left and right banks of the VR30DDTT engine to quickly release unnecessary boost pressure from the left and right turbochargers, reducing the burden on the turbochargers (when the throttle is off).
  • The hose between the turbocharger and intercooler is changed to a special 4-ply silicone hose and the SQV4 is installed.This also strengthens the hose section.
  • All parts other than the SQV4 main unit are black in color, making the SQV4 main unit stand out.
  • The return hose is a specially molded silicone hose, designed to fit snugly in the engine bay.
