Gasket, vent window inner — a genuine BMW part, number 51 37 8 252 625. The number stamped on the part is 51378252625; BMW's catalog files it under the short number 8252625. You will find it on our Interior Body shelf, under Other Body equipment parts.
It fits the E46 coupe (323i, 325i, 328i, 330i and M3, 2000–2006), with the M52, M54, M56 or S54 engines — and the European-market versions.
BMW draws it on the Door Window Lifting Mechanism Rear (51_3687) diagram. BMW's catalog calls for two of these at each place it is fitted. It weighs about 740 g (1.6 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
