Another unique design by Forge Motorsport. This boost tap will fit the FFV (Flexible Fuel Vehicles) including the Audi A4, A5 and Q5. This part allows easy fitment of a boost gauge, water meth pressure sensor or a dump valve to the 2.0T engine. The boost tap itself can be installed without tools in under 10 minutes and is fully reversible should you ever wish to remove it.  Complete with installation instructions. This is also referred to as the Audi B8.5 boost tap but will not fit all B8.5 vehicles, to further help identify if this will fit the 2.0T you have, please see the engine bay picture. Fitment: 2012-on Audi B8.5 A4,A5 and Q5 with the 2.0T engine The part fits many engines within these years. They are ‘FFV’ or ‘Flexible Fuel Vehicles’. To double check, all of the FFV’s have  a sticker inside the petrol cap saying ‘E85 compatible’ . They should also have ‘E85/Gasoline’ written on the petrol cap itself. The final check is that all the FFV’s have a metal intake manifold rather than plastic.
