Genuine BMW part 17 13 7 578 663: Filler neck. The number stamped on the part is 17137578663; BMW's catalog files it under the short number 7578663. You will find it on our Cooling System shelf, under Expansion tank. BMW has since replaced it with 7647275.

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

BMW draws it on the Expansion Tank/Tubing (17_0515) diagram. It weighs about 250 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.
