This is a genuine BMW rubber Ring, part number 18 30 1 703 634. You will find it under Exhaust (Suspension parts exhaust). It supersedes the older number 18 21 1 723 646, so a part carrying that number is the same part.
Fits E36 320i, 323i, 325i, 328i and M3 (1992–1999), sedan, coupe, convertible and touring, with the M50, M52, S50 or S52 engines.
BMW draws it on 5 drawings, among them Catalytic converter/front silencer and Exhaust Pipe Front Silencer. BMW's catalog calls for two of these at each place it is fitted. It weighs about 33 g (under 0.1 lb).
Out of stock. Request it and we will notify you when it is in stock.
