I tried a K&N in an '89 Jetta GL. When I put it in I also cleaned the whole intake tract to the throttle body. After about 6 months I did the same again. The stuff I cleaned from the intake tract felt far more gritty between my fingers. I ran it for another 3 months, found more grit. Then I went back to paper. Next time I replaced the filter there was no grit. This was in California. I have an Amsoil (oiled foam) filter to experiment with in my current car once I put in the 2L block.
I also remember the K&N being oiled thin cotton, not oiled foam. I have also seen experimental data indicating that K&N did not have a measureably lower pressure drop across the filter element that a paper one did. No pressure drop difference means no flow difference. I cannot remember the source for this but it was on the net somewhere.
