MB changed oil filter suppliers around 10 months ago to a smaller
compact style that uses a different style removal cap.
This only applies to the metal canister filters for the M102/103
motors. This is PN# 103 589 03 09 00.
The older (and cheaper) 103 589 02 09 cap will still work on all
the 88' to current cars that use the plastic cap with replaceable
filter insert. (except diesels of course!)
