Sound insulating tunnel rear — a genuine BMW part, number 51 48 1 873 027. The number stamped on the part is 51481873027; BMW's catalog files it under the short number 1873027. You will find it on our Interior Body shelf, under Other Body equipment parts. BMW has since replaced it with 1881159.

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

BMW draws it on the Sound Insulating Front (51_1824) diagram. It weighs about 914 g (2.0 lb).

We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
