Engine Air Filter Basics for Elgin

Today in the McLean Auto Repair car care blog, we want to talk about your engine air filter. That's the filter that cleans the air before it's burned in your engine. Elgin residents wonder how often they should change their engine air filter. The simple answer is: when it's dirty. That's a function of how much air has passed through the filter, so your service advisor will recommend a mileage interval for replacing the air filter. But you can imagine that how dirty the air is would affect how quickly the filter gets filled.

If you drive where there's lots of dust, pollution or pollen around Elgin, your engine air filter will get dirty more quickly and need to be changed sooner. That's why we check the air filter with every full-service oil change at McLean Auto Repair in Elgin. We can visually tell if the filter needs to be changed. Your filter can only hold so much dirt. Once the filter is full, dirt will pass through to the engine. This dirt gums up the combustion chamber, hurts fuel economy and may cause damage. It can also contaminate the Mass Air Flow Sensor which will affect drivability and can be fairly to replace.

A dirty air filter would also restrict the amount of air that gets to the engine which hurts fuel economy. We can replace your engine air filter with one that matches the factory specifications or you can upgrade your filter for enhanced performance. So when your friendly and knowledgeable McLean Auto Repair service advisor shows you your dirty air filter, you know how it is time to get it replaced.
