Your recall is poor. They opened a bunch of different filters. The usual German filters, like Hengst, Knecht and Mann, were filled with floor sweepings from cotton mills. Their fill included sticks, bugs, dust, all sorts of crp.

Fram, specifically the ones made in Turkey, used nice clean material. I've preferred Fram for my Mercedes diesels ever since. It has to be fifteen or twenty years and half a million miles or more. The above comment about restriction is complete nonsense. The cumulative cross section of all those holes FAR exceeds the cross section of the filter outlet (look at the top and bottom of any filter). Everything else is just sniping. Recently I've switched to Wix because of availability, but I won't use the German brands.

The original thread was off-board and long-gone, but here is one of several old threads that covered this:

Just look at the photos, and you'll be convinced.
