Original BMW Engine Oil Filler Cap, BMW 3 to 8 Series, M3, M5, X3, X5, Z3, Z4, and Z8 (1990–2010)

BMW part number 11-12-7-509-328 is a Genuine BMW cap for the oil filler opening, shared across a wide range of four-cylinder, six-cylinder, V8, and V12 engines in BMW 3 to 8 Series, M3, M5, X3, X5, Z3, Z4, and Z8 models from 1990–2010. An oil filler cap closes the fill opening on top of the engine, keeping oil in and dirt out between oil changes. This cap weighs 48 g, and BMW began producing this number in March 2000. It is sold as a single piece.

Original BMW Parts carry a 24-month parts warranty.

BMW's parts data covers this cap on a long list of engines: M42, M43, M44, M50, M52, M54, M60, M62, M70, and M73, plus the N62 and N73 V8 and V12 engines, the S50 in the M3, and the S62 in the M5 and Z8. A few model names in its fitment run on more than one engine generation, which is why the 525i appears for 1991–1994 and again for 2004–2005. The engine code matters more than the model name here, so check it against the fitment table.
