Quite a few differences. The pressure relief bypass on the German ones are a different setup. The baseplates are completely different and the filter element is different.
Bosch & MANN oil filters are just rebadged Purolator filters here in the USA. You can still find places online where you can buy the German filters. I'm pretty sure NAPA Online carries both "Made in USA" and "Made in Germany" Bosch products. I think autopartswarehouse.com does too.

The Mann filters I purchase for my MINI & VW from germanfilters.com are from Germany & Austria. So you might check there as well for the the real MANN Euro filters.
The Mann filters I have been ordering online have all been made in Mexico. Are these as good as the German-made ones?

Maybe you could cut one of these and an American one open so we can see the differences.

Very probably they are about the same in performance.
Assuming that the cases don't burst and the bypass valves work, the two measures of "goodness" are efficiency and capacity.
Efficiency measures what percentage of a given particle size is removed in a pass through the filter:
e.g., 95% of 20 micron particles.
Capacity measures how many of these particles can be removed before the filter "plugs" and begins to bypass.
With the common cellulose fibers in most filters they tend to be pretty much alike at a given price point.

These filters he uses are probably the cartridge type vs screw-on can type, and no cutting should be required to see the differences on his MINI/VW filters.

I assume the American Purolator built one is the marginally better dirt trapper, but I haven't tested Mann versions of Purolator products, nor a cross section of German Mann filters.
I would guess the German Mann is better suited to very long replacement intervals.
