Forge Motorsport’s boost pipe for the E9X 335d models. This hose was designed to overcome the shortfalls of the original hose, namely boost and oil leaks as pictured.

The Forge solution is a 4-ply fluorosilicone hose to not only withstand the temperatures and pressures, but the oil exposure too. It is combined with CNC alloy couplers for perfect fitment. Comes complete with instructions.
