Engine Oil Drain Plug, M22x1.5 - 2002, E21, E24, E9

This is the large M22 oil drain plug found on older M10, M20, and M30 engines. It's a super-large M22x1.5 thread size instead of the smaller M12x1.5 that came later. 

Please note: 22x27 gasket ring / crush washer sold separately. See part # 07119963355 for the aluminum version.

This part is made by Corteco, an original supplier to BMW for gaskets and hardware.
