This is a genuine BMW rubber Ring, part number 18 21 1 105 638. The number stamped on the part is 18211105638; BMW's catalog files it under the short number 1105638. You will find it on our Exhaust shelf, under Other Exhaust system parts. It supersedes the older number 1105677, so a part carrying that number is the same part. BMW has since replaced it with 1105635.
BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.
BMW draws it on 20 diagrams, among them Suspension parts exhaust (18_0004) and Exhaust system (18_0007). It weighs about 40 g (under 0.1 lb). It also comes in BMW kits Set mounting parts (1175762) and Set mounting parts (1175763) and 5 more.
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
