This is a genuine BMW air channel, part number 12 31 1 747 185. The number stamped on the part is 12311747185; BMW's catalog files it under the short number 1747185. You will find it on our Electrical shelf, under Alternator with motor and mounting.

BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.

BMW draws it on 4 diagrams, among them Alternator, individual parts 100A (12_0491) and Alternator Parts 140a (12_0492). It weighs about 53 g (0.1 lb).

We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
