In order to run, the engine needs a precise mixture of fuel and air. When outside air is drawn into the engine, the air filter prevents harmful dirt and debris from entering the system.

The filter will become dirty, but drivability problems are not typically noticed except in the extreme. Decreased fuel efficiency, stumbling, or rough running may be noted with a severely clogged air filter.

Can I drive with an air filter problem?

RepairPal Recommendations for air filter issues

Most engine air filters are very low cost, when going through the trouble to inspect them, they should be replaced unless they have been recently serviced.

What to look out for when dealing with air filter issues

The air filter box cover is attached to the engine intake tube. Often, this tube will hold additional sensors such as the Mass Airflow Sensor (MAF) or intake air temperature sensor. When servicing this part, it is important not to disconnect or damage anything in the vicinity. There may also be vacuum hoses in the servicing area. Failure to take care or reconnect lines and hoses in this area may cause running issues and the Check Engine Light to illuminate.

Can I replace the air filter myself?

Most engine air filters are extremely easy to replace. But before ordering parts or attempting this service yourself, it is important to look for the correct procedures to replace the engine air filter on your specific car. Certain models will require tools in order to access the air filter box as today's engine bays become more complicated and crowded.
