This is a genuine BMW sound insulating trunk floor, part number 51 48 8 100 400. The number stamped on the part is 51488100400; BMW's catalog files it under the short number 8100400. You will find it on our Interior Body shelf, under Other Body equipment parts.

BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.

BMW draws it on the Sound insulation (51_1821) diagram. It weighs about 735 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.
