Your engine's air filter should typically be replaced every 15,000 to 30,000 miles, depending on driving conditions. If you drive in dusty or sandy environments, you may need replacements more frequently.

A clogged air filter reduces engine efficiency, impacts fuel economy, and can harm performance. Replacing it is a simple, affordable maintenance task that pays dividends.
