Must be a pretty clean place! I usually check the engine air filter every oil change and change it when it's dirty. I use cheapo Ultra 8 filters now. #3600528. They're cheaper than the wix filters but they don't have as much material to catch dirt and need to be changed more often. They feel cheap, pretty flimsy. But gotta save a penny somewhere.
