Sold as part of these kits
Genuine BMW part 18 21 4 490 157: Base. The number stamped on the part is 18214490157; BMW's catalog files it under the short number 4490157. You will find it on our Exhaust shelf, under Other Exhaust system parts. It supersedes the older number 1245524, 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 15 diagrams, among them Suspension parts exhaust (18_0004) and Suspension parts exhaust (18_0011). It weighs about 12 g (under 0.1 lb). It also comes in BMW kits Set mounting parts (1175762) and Installing Set Exhaust Suspension (9056634).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
