On the 944 board when I was over there they had some great pictures of engines torn down that had been running K&N's (I have no idea about how they were maintained..the filters that is).
Anyway, the cylinder walls in the K&N equipped engine showed a lot of surface damage from particulate introduced into the cylinder. Those pictures alone insured I would never run them. Sadly, however, I do run them on my 911 but I'm doing everything I can to get paper filters for my weber rain shields. In fact a few of us are looking for someone to make them.
