What Is an Engine Air Filter?Your engine breathes air the same way you do. While you breathe air through your nose, your car breathes in through the air intake system. This is a series of plastic tubes that bring air from outside your car into the engine. A simple filter, usually made of paper, sits near the beginning of your engine’s air intake system. It makes sure that only clean air goes into your engine, with no dust or debris that might cause damage to sensors or the engine itself. It works rather like the face masks we all got used to wearing in 2020. A mechanic will take very little time to replace this filter, charging maybe half an hour of labor. Even a quick lube shop can do it quickly while you get your oil changed and will often recommend it, whether you need it or not.
What Happens If You Don’t Change Your Car’s Engine Air Filter?What happens if you breathe dirty air? You cough, sputter, and get dirt into your lungs. That’s also what happens to your engine if you don’t change the engine air filter. The engine may run rough. You may lose power and/or fuel economy. The check engine light may turn on, particularly if your engine misfires, or indicates a lean condition, which is a sign that your mass air flow sensor is dirty or has failed completely. A dirty air filter can cause more serious problems down the road, but replacing it is so cheap (around $20-$40 for parts) and easy to do, you might as well do it yourself.
How Often to Replace the Engine Air FilterGenerally speaking, you should replace your engine air filter every 12,000 to 15,000 miles. This may vary, however. Check your vehicle maintenance schedule in your owner’s manual, and go by what the manufacturer recommends. Also, if you find yourself often driving in dirty or dusty conditions, check your air filter more often than recommended, and replace it as needed.
