The Active Autowerke N55 Charge Pipe is constructed from all aluminum, and the connection to the throttle body is CNC machined to duplicate the factory fit as well making a tight, reliable seal.
Added features were also implemented to further enhance the BMW N55 performance. A large 3.00 inch all aluminum tubing would be the size used without any restrictions or reduced pipe sizes. This would enhance the airflow and peformance.
Owners of BMW with the N55 engine understands that additional power can be reliably maintained with the use of Water/Methanol injection as an added feature. However, the N55 current does not have a reliable source to accomodiate the application of a Water/Metahol nozzles.
The Active Autowerke N55 Charge Pipe has a proper proviison for this specific application. A boss with two separate ports are provided upstream where the injected mix of water/methanol can properly atomize before entering the engine. The thread depths for the water/metahnol nozzles are also checked to allow for a proper spray pattern without hitting the inside walls of the threaded holes.
The BMW N55 engine does not utilize external diverter valves like it's N54 predecessor. Rather, the N55 diverter valves are built internally inside the engine turbo compressor housings and no in the charge pipe. As such, there are no provisions to add larger BOVs.
