FMBGFK9 -; Turbo Valve for Audi RS3 (8V) The Forge Motorsport Turbo Pressure Valve for Audi RS3 (8V) allows the mounting of a pressure gauge or anything that plugs into the turbo circuit, e.g. a water/methanol pressure sensor, on 2.5 TFSi engines. Before, it was possible to get the turbo pressure below the air flow meter, but since the manifold has changed shape, this is no longer possible. This new turbo valve can be installed in less than 10 minutes and does not involve irreversible modifications, you can easily disassemble it if necessary. The kit is complete and contains assembly instructions. *Not compatible with DAZA engine (TTRS from 2017 and RS3 version 2017)
