OEM air filter. If an air filter is doing it's job, it will get dirty. As a filter gets dirty, the amount of air that can flow through it is reduced. Without the proper amount of air, the engine will not be able to produce the power it should; nor it will be as fuel efficient as it should be. Make sure your car is breathing only the freshest air with this high quality OEM air filter.
