What Does a Car Engine Air Filter Do?

A clean air filter improves the quality and quantity of clean air entering the engine, and this improves the engine performance and efficiency. Dirty air filters will not allow the same amount of air to enter the engine as a clean one would. Studies have shown that fuel economy can be improved by up to 14 per cent with a clean air filter.
