Changing your air filter is one the most important things to keep in mind during the fall. Not only will this regular service improve performance and efficiency, it can also help to extend the life of your car. Read on to learn more about the benefits of changing your air filter.
According to Cars Direct, one of the major benefits of replacing your air filter is increasing efficiency. Believe it or not, a dirty filter can clog airflow and reduce fuel economy by up to 14 percent. Because cars rely on smooth air flow in order to maintain combustion, a poor air supply could lead to poor gas mileage.
In addition to improving gas mileage, changing the air filter will reduce emissions as well. When air supply is low during the combustion process, this can lead to a rich air-fuel mixture. Not only will this increase the amounts of particulates that come out of the tailpipe, it can also damage emissions-control components like the catalytic convertor or O2 sensors.
When should you replace your air filter? The average driver should get a new filter every 12,000 to 15,000 miles. That’s roughly once a year. Even if an air filter looks clean, it’s a good idea to get a new one when the time comes. If you’ve had your filter for less than a year, you can also spray it out with compressed air to try and eliminate any buildup.
