Today I want to talk about your engine air filter. That’s the filter that cleans the air, before it’s burned in your engine. Pop Quiz! How often should you change your engine air filter?

So the manufacturer will recommend a mileage interval for replacing the air filter, but you can imagine that how dirty the air is would affect how quickly the filter gets filled.
