Air Filter Replacement near Chicago, Illinois

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.

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.

Failure to take care or reconnect lines and hoses in this area may cause running issues and the Check Engine Light to illuminate.

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.
