I know this is a stupid question, but I am still a noob - about how often should I replace air filters? I know I should be checking them every couple thousand miles, but about when should I expect to change them out?
I'm going with afe when I need some new filters. I don't think there's enough of a power gain to justify tossing the old ones before they're spent in the name of performance. I'd love to stumble upon a set of black COBB tubes somewhere...
