Turbosmart Type 5 Plumb Back Recirculating Diverter Valve (Blue) - Subaru Impreza WRX STi GC-GD
Turbosmart Type 5 Plumb Back Recirculating Diverter Valve (Blue) - Subaru Impreza WRX STi GC-GD
The Turbosmart Type 5 Plumb Back Diverter Valve is made from durable billet aluminium designed to offer superior flow and performance.
A fully recirculating valve that offers a quiet alternative to atmospheric valves.
The Turbosmart Plumb Back Diverter Valve system vents all excess pressure back into the intake system and is ideal for cars with sensitive airflow systems and off road applications as the fully sealed design of the Plumb Back valve prevents any foreign matter entering the system.
When accelerating the turbocharger produces compressed air which supplies the engine. When you lift off the accelerator the throttle butterfly closes and the boost has no escape route, so it backs up through the intercooler and causes back pressure, preventing the turbo from spinning, also known as compression stall. By installing a dump valve, every time you release the throttle excess boost pressure will be released creating a significant reduction in turbo 'lag' contributing towards faster pick up between gear changes.
Easy to Install and Setup.
