There are also internal differences in VW drop in filters (A4). As I previously posted I had a new drop in unit with the same VW part number that did not have the beefed up internal shaft of a newer one that I pulled out when doing a recent oil change. Other than that, the units where the same. I assume that VW had beefed up the internal plastic for some reason but no one seems to know why...
