This is a genuine BMW air filter element, part number 13 72 1 730 946. The number stamped on the part is 13721730946; BMW's catalog files it under the short number 1730946. You will find it on our Air Intake shelf, under AIR CLEANER. BMW has since replaced it with 1730449.

It fits every E36 body style (320i, 323i, 325i, 328i and M3, 1992–1999), with the M50, M52, S50 or S52 engines — and the European-market versions. It also fits the E46 sedan, coupe, convertible and touring (320i and 323i, 2000–2005), with the M52 or M54 engines — and the European-market versions.

BMW draws it on 12 diagrams, among them Service, engine oil / inspection (02_0008) and Suction Silencer/Filter Cartridge (13_0370). It weighs about 209 g (0.5 lb).

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