The problem is that people think filters are all the same (and they can be, dimensionally) when in fact the filter medium, pressure limits, etc, can vary widely.

Be careful of companies that are reported to 'build the filters for BMW' such as Mann and Mahle as these are often a lower quality standard that the actual OEM filter. Not picking on those two any more than the others, but in my business we regularly see oil filter companies producing multiple product lines with different internal specifications.
