Every vehicle GM makes has air filters -- both a cabin air filter, which helps keep dust and allergens from accumulating in your HVAC, and an engine air filter, which helps keep particulate from building up in engine parts like your air intake, fuel injectors, and spark plugs. They're both vital to keeping your AC and heating systems and engine working right. If your vehicle didn't have either, those contaminants would start to wear out those parts and more double quick. However, even the best air filters GM makes wear out with age. If they clog, more problems follow -- everything from higher emissions and lower fuel efficiency to a stressed and misfiring engine. Even your HVAC can stop working as well. The best way to keep all this from happening? Change both air filters regularly. It's usually recommended every 12,000 to 15,000 miles or so.
