Air filters may seem small, but they’re actually vital components that keep your vehicle running smoothly. This guide goes over what your car’s air filters do — and when you should consider changing them out for new ones.
When air enters your car’s cabin through the heating, ventilation, and air-conditioning system, it will go through your cabin air filter.
Just like your cabin air filter, your engine air filter cleans the air. This time, though, it cleans the air that enters your engine.
It’s easy to discover when you should change your car’s air filters — just check your owner’s manual.
