In another thread on here I mistakenly posted that I had about 100,000 km on the air filter in my Civic, but further investigation showed I actually had 61,000. Because I had already bought a new Fram air filter though, I decided to replace the one in the car. It was in there for 4 1/2 years and sees lots of road salt in the winter time so I really was surprised to see how clean it looked! Based on this, I feel like I can easily go 100,000 km between changes on this car under my driving conditions (and I probably won't even have the car that long) I did not knock any dirt out of this filter before taking this picture, this is exactly how it came out of the airbox:
