Forge Motorsport"s New 2.0L VAG Valve Design

Based out of the UK, Forge Motorsport has set the standard in blow off valve and diverter valve manufacturing for a very very long time.  Christ I even had one of these back in 2002 for my Subaru WRX!  So how does the best get made better?  When you make the world’s finest Volkswagen Audi Group engine dump valve already, the only way to make it better is to start over and make it even better. Now with improved sound, full electronic integration and enhanced styling, Forge Motorsport’s latest VW Group dump valves truly set the standard.

Forge Motorsport offer this valve option for the 1.4T, 1.8T & 2.0T FSI and TSI engines, including the late 2011-2013 2.0 engine fitted with the IHI turbo, (the 1.4T needs additional fitting kit FMBGFK3) found in a wide range of vehicles from VW, Seat, Skoda and Audi.

This valve represents the latest evolution of part number FMFSITAT, and is a hybrid of sorts, that combines our existing full replacement solenoid controlled recirculating valve with our blow-off valve adapter. The result is a full replacement atmospheric blow-off valve that integrates seamlessly with the OEM electronics and results in absolutely no fault codes, no check engine lights, and no detriment to the performance of the vehicle in any way. Like our full replacement recirculating valve option, the FMFSITVR, the FMFSITAT is fully engineered to remedy the failure issues experienced with the OEM solenoid valves when their diaphragm may rupture which would effectively result in a boost leak.

Forge valves use full billet alloy construction with a piston based internal design that provides for significantly improved reliability over the OEM valves along with lightning fast response. This valve is particularly well suited to the B7 and B8 chassis Audi A4 and A5 with the 2.0T engine. The valve mounting location on these vehicles is positioned particularly close to the frame rail of the chassis, and the overall installed height of our standard replacement valve and spacer combination is such that it conflicts with the chassis at this location.

Note: This will ONLY fit the 1.4 turbo engines up to early 2013, where the turbo is mounted at the front of the engine bay. It will not fit engine codes CMBA & CXSB
