So today I went to change out my air filter with a new KN filter I just bought and it looks like the previous owner already had one in there. Has maybe 7000 miles on it and as you know KN filters are lifetime. This is for the used filter not the new one I just bought. 20 bucks plus shipping from 93726. I checked and USPS from here to cross country was 9 bucks so its not too bad.
