Engine air filters typically need replacement every 15,000-30,000 miles, though dusty environments may require more frequent changes. A clogged filter reduces fuel economy, engine performance, and air quality inside your cabin.

Cabin air filters (which clean the air you breathe while driving) often need attention every 12,000-15,000 miles. Both are quick, affordable replacements that make a real difference. Castle Chevrolet North's Service team can check your filters during any visit and swap them out as needed. Call (847) 439-0900 to ask about your Chevy's air filter schedule.
