Turbo tuning parts > Forge Blow off valves | FIAT/ABARTH (Coupe 2.0 Turbo 20V) | FMDV004

• Suitable for most turbo cars with an Air Flow Meter

Made from billet aluminium, this atmospheric diverter valve dumps the charge-air to atmosphere creating the "Whoosh" 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. This prevents our diverter valves suffering any of the failures associated with single piston and diaphragm type diverter valves.
