Engine Air Filter

November 3rd, 2018

The Engine Air Filter cleans the air before it's burned in your engine. Many people in Ashland 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 vehicle manufacturer 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 in Ashland where there's lots of dust, pollution or pollen, 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 Air Park Auto Service. We can visually tell if the filter needs to be changed.

The fuel filter catches dirt and contaminants. When it's clogged, your engine may not be able to get enough fuel and could sputter. Many fuel filters have a bypass valve that allows unfiltered fuel past when the filter's clogged.

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 expensive to replace.

Fuel will cause gum and varnish to build up in the fuel intake system. A professional fuel system cleaning will remove the gunk to keep fuel flowing freely and help prevent contamination from reaching your fuel injectors and your engine.

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 Ashland, VA, service advisor at Air Park Auto Service shows you your dirty air filter, you know how important it is to get it replaced.
