Your engine air filter typically needs replacement every 15,000-30,000 miles, depending on driving conditions. Dusty or rural driving may require more frequent changes.

A clogged air filter reduces engine efficiency, lowers fuel economy, and can hurt performance. It's one of the easiest maintenance items to address and keeps your engine breathing freely.

Castle Kia McHenry's technicians check your air filter at every service and replace it when needed with genuine OEM parts. We'll also check your cabin air filter (which keeps your interior air clean) at the same time. Call (815) 453-8566 to schedule a quick inspection, or ask about it at your next visit.
