When to Replace Your Engines Air Filter?

Today we want to talk about your engine air filter. That’s the filter that cleans the air before it’s burned in your engine. People 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 manufacturer will recommend a mileage interval for replacing the air filter. But if you drive in areas with heavy dirt, dust and smog, that will affect how quickly the filter needs replacement.

That’s why we check the air filter with every full-service oil change. 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 and hurts fuel economy and may cause damage. It can also contaminate the Mass Air Flow Sensor which will affect drivability and can be fairly expensive 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 service advisor shows you your dirty air filter, you now know how important it is to get it replaced!
