The Forge Motorsport boost pressure fitting is designed for vehicles with the 2.0T FFV (Flexible Fuel Vehicle) engine. It enables easy connection of a boost gauge, a pressure sensor for a water/methanol injection system or a blow-off valve.
The fitting can be installed without tools in less than 10 minutes. Installation is fully reversible, so it can later be removed without permanent modifications to the vehicle. The kit includes fitting instructions.
The product is also known as an Audi B8.5 fitting, but it does not fit all B8.5 vehicles. It is intended for versions with the 2.0T FFV engine, which have a metal intake manifold. FFV vehicles have an “E85 compatible” sticker inside the fuel filler flap and an “E85/Gasoline” marking on the fuel cap.
