Bottom part — a genuine BMW part, number 12 90 1 704 790. The number stamped on the part is 12901704790; BMW's catalog files it under the short number 1704790. You will find it on our Electrical shelf, under Other Engine Electrical System parts.

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

BMW draws it on the E-Box-Ventilation (12_0378) diagram. It weighs about 265 g (0.6 lb).

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