Are you noticing a lot of dust collecting on the dashboard of your car? It may be time to get that air filter replaced.
The air filter is a filter that is typically either made out of fiber or paper and is designed to clean particulates out of the intake air stream prior to the intake manifold. They act as the last chance to rid the air of everything that could pass in to the small, sensitive passageways and sensors of the intake system. Check the air filters regularly to prevent dust and road grime from getting into these passageways. Refer to your owner’s manual for regular maintenance intervals.
