So I have a Donaldson M100465 which is starting to leak from the bottom, I am thinking about getting the M100463 (high flow) or the M100944 (oe recommended for higher hp engines) and was wondering if anyone has or had experiences with either on a cm870 at 500hp/1850ftlbs with the mandate gone, or if I should get another m100465?

Personally, I would stick with what Cummins or the OEM recommends, but that is just me having been this road with other parts.

Usually I stick with the oem replacement parts also, but i went ahead and installed the m100944 I took at look at it and the m100465 and they look very similar inside. So far it's doing well not overboosting or anything like that.
