The Active Autowerke N55 Charge Pipe has a proper provision 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/methanol nozzles are also checked to allow for a proper spray pattern without hitting the inside walls of the threaded holes.
The Active Autowerke N55 Charge Pipe is a designated product designed from inception to cure and eliminate this problem on your BMW.
Constructed from all aluminum makes this charge pipe almost indestructible. The connection to the throttle body is a CNC machined part to duplicate the factory fit as well making a tight, reliable seal. The BMW N55 engine does not utilize external diverter valves like it's N54 predecessor. Rather, the BMW N55 has diverter valves that are built inside the engine turbo compressor housings and no in the charge pipe. As such, there are no provisions to add larger BOVs.
The factory throttle clip is not included with the N55 Charge Pipe.
