Genuine BMW part 18 30 7 620 549: Hex nut with flange. The number stamped on the part is 18307620549; BMW's catalog files it under the short number 7620549. You will find it on our Exhaust shelf, under Suspension parts exhaust. It supersedes the older number 1711954, so a part carrying that number is the same part.
It fits every E36 body style (318i, 318ti, 320i, 323i, 325i and 328i, 1992–1999), with the M40, M42, M43, M50 or M52 engines — and the European-market versions.
BMW draws it on 85 diagrams, among them Exhaust manifold (11_2639) and Exhaust manifold (11_6006). It weighs about 10 g (under 0.1 lb). It also comes in BMW kits Set of add-on parts, silencer (0141657) and Set of add-on parts, silencer (0141658) and 38 more.
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
