This is a genuine BMW ventilation hose, part number 12 90 1 433 121. The number stamped on the part is 12901433121; BMW's catalog files it under the short number 1433121. 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 Control unit box (12_0647) diagram. It weighs about 211 g (0.5 lb).

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