HKS Super SQV4 (Silver) Fairlady Z RZ34 71008-AN030V

The HKS SUPER SQV (Sequential Blow-Off Valve) uses a unique two-stage sequential valve structure with a primary valve and a secondary valve, and achieves delicate pressure control over a wide operating range from low boost to high boost with a differential pressure control system.
In addition, the “relief-less operation method” that differs from the structure of a typical blow-off valve suppresses relief during high boost and maximizes charge response when repeatedly switching between boost and release with the throttle ON/OFF.

 

 

 

 

■ 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.
