The purpose of an air filter is to remove things like dust, dirt, and mold before it enters your vehicle's cabin. Air filters usually last for around 15,000-30,000 miles. But, if you spend a lot of time on dirt roads, you'll want to check it more often. If your mileage drops, or if black smoke is coming out of the exhaust, it's likely time to replace your air filter. For a consistent level of quality that's known to last, experts always recommend OEM parts. At McGeorge Toyota, your satisfaction is guaranteed.
