Dual Piston 25mm Blow Off Valve (Universal)

Description

Universal Blow Off Valve, suitable for most turbo cars with an Air Flow Meter.

Made from billet aluminium, this atmospheric Dump Valve dumps the charge-air to atmosphere creating the dump sound when the throttle is lifted. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably.

Unlike single piston or diaphragm diverter valves, this uses counter balanced springs and dual pistons to prevent the valve from leaking air into the intake system at idle or partial throttle situations. This prevents our diverter valves suffering any of the leaks associated with single piston and diaphragm type diverter valves under such situations.

Only available in polished Silver, comes with a spare spring for applications that require a stiffer spring.
