25mm Universal Aluminium Single Port Diesel Blow Off Dump Valve - Black.
 
Made from billet aluminium, this SuperSonic diverter valve  vents some to the atmosphere to create the desired *woosh* sound.. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably and turns heads! It also allows adjustability to the preload, to set it up to work in harmony with your driving style and engine.
 
Features:
The dump valve can be fully adjusted to suit your specific boost pressure / application
This valve is rated to 2.0 Bar / 30 PSI at full adjustment, so is more than capable for most 25mm applications
Universal fit all application with 25mm connections
Made from strong aluminium to guarantee quality
Coated with a strong black hard anodized exterior to keep it looking fresh for years
