Your engine's air filter protects your engine from dust and debris-and a clean filter helps your engine breathe and run efficiently. Most vehicles need an air filter replacement every 15,000 to 30,000 miles, though this varies based on driving conditions. If you drive in dusty areas, you may need more frequent replacements.

Signs your filter is due include reduced fuel economy, rough idling, or reduced acceleration. A fresh air filter is an affordable way to maintain performance and prevent engine strain.
