Your engine air filter keeps dust, pollen, and debris out of your engine. A clogged filter reduces airflow, hurting fuel economy and performance. Replacement intervals vary by driving conditions-typically every 15,000 to 30,000 miles-but dusty environments may require more frequent changes.

During your next visit or service appointment, we'll inspect it for you. Call (847) 593-4700 to schedule or ask about our maintenance packages-we'll keep your VW running smoothly.
