The factory plastic charge pipe is one of the known weak points of the N55 engine in F2x, F3x and F87 vehicles. Due to constant heating and cooling, the factory coupler eventually becomes brittle, cracks and fails – usually together with a loss of boost pressure. This aluminium replacement solves the problem with a CNC-machined coupler that does not become brittle like the original.
Important: The pipe is not suitable for vehicles with xDrive. On xDrive vehicles, the steering rack is installed where the pipe needs to run, leaving insufficient space for installation.
