You change your air filter every 3000 miles?
Most people replace them far too often, since a dirty filter will trap more dirt. I just changed the air filter on my 95 Firebird at 83k and I believe it was still the original one! It was very dirty, but oil analysis showed it stopped dirt well, and I put the new filter on at the dragstrip and my trap speed only went up by 0.2mph, so that dirty filter was only holding me back by about 1 or 2hp at the most.quote:

I've been using K&N air filters for the past 15 years and actually forgot how often I used to replaced papers filters when I did use them. How often are you supposed to replaced paper air filters?
