Original BMW M14 x 1.5 Engine Block Drain Plug for BMW 1, 2, 3, 4, 5, 6, 7, 8 Series, M, X, and Z Models (1975–2025)

Original BMW screw plug 07-11-9-904-539 is an M14 x 1.5 threaded drain plug that closes the drain port on the side of the engine block across a wide range of BMW models from 1975 to 2025. It is used to drain coolant from the block during a coolant service. It weighs 26 grams. The plug has a zinc-nickel finish, and BMW specifies it as free of hexavalent chromium. It is made in Germany and sold individually, without a sealing washer. A block drain plug threads into a port low on the engine so coolant trapped in the block can be emptied, something a radiator drain alone cannot do.

Original BMW Parts carry a 24-month parts warranty.

BMW production of this plug began in September 2003. It supersedes 07 11 9 902 291 and is interchangeable backward, so it can replace the earlier plug on older cars. Another cross-reference number for this part is 07 11 9 919 158. The plug is usually a lifetime piece. Replace it when the threads are damaged or the plug is corroded. The gasket is a separate part and must be ordered with it.
