This is a genuine BMW pipe, part number 64 11 1 378 203. The number stamped on the part is 64111378203; BMW's catalog files it under the short number 1378203. You will find it on our AC & Climate Control shelf, under Other Heater and Air Conditioning parts. It supersedes the older number 1468483, so a part carrying that number is the same part.

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

BMW draws it on 7 diagrams, among them Heater radiator Behr (64_0121) and Heater Radiator Air Conditioning (64_0174). It weighs about 80 g (0.2 lb).

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