Rubber Ring — a genuine BMW part, number 18 20 7 578 239. The number stamped on the part is 18207578239; BMW's catalog files it under the short number 7578239. You will find it on our Exhaust shelf, under Exhaust system, rear. It supersedes the older number 1439561, 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 9 diagrams, among them Exhaust system, rear (18_0305) and Rear silencer (18_0365). It weighs about 50 g (0.1 lb). It also comes in BMW kits Set of add-on parts, silencer (0151438) and Set of add-on parts, silencer (0151439).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
