I put 90k miles on my first air filter and I got 88.7k miles on this one. I change the air filter at six years or when my restriction gauge shows I have a restriction. So far in a little over 12 years and 200k miles the air filter's(two) has yet to show a restriction. I check the filter every oil change(around 7500 miles). This is on my S2000 and I can check the filter without letting any dirt get past the filter, its a large cone filter.
