Audi long ago went to stocking the same filter for most if not all of the
5-cylinder cars.  You can do the same.  Save yourself a whole lot of
scratch and get a Mobil 1 or Amsoil filter, for example.

The main features you want:
-large filter area
-filter held together with metal or plastic, not cardboard (fram, ugh!)
-anti-drainback valve (possibly visible around the edge holes)
-bypass valve (visible through the center hole, down at the bottom.)
-filter body that feels solid (Fram and others used to skimp on the metal-
some would fail under the higher oil pressures used in European engines.)
