Custom-designed replacement oil cap for the legendary BMW M20 engine. Uses the original screw-in mechanism—no sketchy press-fit, no glue, just a perfect OEM-style fit. Finished with a BMW logo for an authentic look.

Fits all M20 engines (E30, E34, E28, and others)

OEM-style screw threads – installs just like the factory cap

BMW logo detail for the proper aesthetic

I made this for display and printed it in PLA, so it’s great for non-running engines or as a showpiece.
If you want to use it on a real, running M20: print in ABS, ASA, or any high-temp material for heat and oil resistance. Not recommended in PLA under the hood!

Perfect for builds, engine displays, or finishing off your classic BMW’s bay with a personal touch.
