Engine air filters typically need replacement every 15,000 to 30,000 miles, though it depends on driving conditions-dusty or high-traffic environments may require more frequent changes. A cabin air filter (for your climate control) should be replaced every 12,000 to 15,000 miles.

A clean air filter improves fuel efficiency, engine performance, and air quality inside your car. Castle Chevrolet North's Service Department stocks genuine Chevrolet filters and can replace them quickly during a routine service.
