A dirty air filter prevents the engine from breathing properly, which can decrease fuel mileage and performance and make the engine work harder than it needs to. Let your vehicle breathe! Change the air filter once a year or when recommended in your owner’s manual. Change it more often if you drive in dirty or dusty conditions.
If your vehicle is equipped with a cabin air filter, change that too. A dirty cabin air filter reduces the airflow through the vehicle’s ventilation system. Cabin air filters help keep pollens, fumes, smoke, and other materials from reaching the inside of a vehicle. See the owner’s manual to determine if your vehicle is equipped with a cabin air filter.
