Your air filter stops debris that comes in through your air intake before it reaches the throttle body or, in some cases, the carburetor. It can stop your engine from filling up with muck, dirt, and dust, but a dirty air filter restricts airflow to the engine, causing a rich air/fuel mixture. When your car runs rich, it burns more fuel and gives off more emissions. If you’ve ever looked at the air filter while changing it, you know just how much dirt it stops—and how dirty it gets. The filter keeps all that muck out of your engine, but a dirty one can clog up your engine’s airflow. Without sufficient airflow, your engine’s fuel air mixture runs rich with too much gasoline.

Signs of a dirty car air filter include poor gas mileage, higher emissions, engine misfires, unusual engine sounds, and trouble starting. These problems only get worse as it gets dirtier and older. In extreme cases black smoke or even flames can come from your vehicle’s exhaust pipe because of the rich air mixture. If you're driving with a dirty engine air filter, it's time for a replacement. This kind of replacement is an easy job for any DIYer. If you don't know how, check out our guide on how to change your engine's air filter, so you can confidently do the job right. After you're done, you'll likely notice your engine running better as it is able to get enough clean air through the intake.

Protect your car from damage down the road with a new air filter from AutoZone. We carry the best brands, so if you’re looking for a K&N air filter, or any other major brand, you can drive confidently on the road ahead.
