Dual Port Blow Off Valve,25mm Turbo Diverter Valve Dump Valve BOV Turbine Relief Valve Blow-Off Valve For VW MK4 Golf GTI 1.8T

• Made from billet aluminium, this DUAL PORT diverter valve allows charge to be dumped the charge-air back into the air intake system to keep the onboard MAF happy, but also vents some to the atmosphere to create the desired *woosh* sound..
• These valves also protect your turbo by reducing thrust damage to turbo bearing typically caused by compressor stalling.
• 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.
