Picked up a new filter from my dealer that is shorter than the one I removed. It also has more passage holes. The old filter was longer and had 4 (I think) oblong holes for passage ways. Anyone know the difference between these parts? I am curious if I have the wrong filter on now.

These are the part #'s direct from Mahle.
The OE #'s we show for the OC 25 are
11421258039
11429061197

The OE# we show for the OC 84 is
11421278059

The OC84 has a thicker housing and will accept a higher pressure. This is mainly used for colder areas. The OC 25 is for the warmer climates and is used mainly in Europe. Our US customers do order both parts, but we do not recommend the OC 25 if you live in the northern part of the US or Canada.
This is a reprint from Mahle.


So if I live in Portland, OR, where I don't plan on seeing temps below 35-40F, am I okay to run the OC25? That is what my dealer supplied. The previous owner was a former BMW mechanic and may have been running the OC84, but I didn't get the part number.
