This is a genuine BMW brake pipe bracket, part number 41 11 8 119 249. The number stamped on the part is 41118119249; BMW's catalog files it under the short number 8119249. You will find it on our Exterior Body shelf, under Other Bodywork parts.
It fits the E36 sedan, coupe, convertible and touring (318i, 320i, 323i, 325i and 328i, 1992–1999), with the M40, M42, M43, M44, M50 or M52 engines — and the European-market versions.
