It all starts with airflow. The more air that your engine breathes, the more oxygen it receives. More oxygen results in a better combustion. Better combustion translates into more power and better fuel economy. This is why your vehicle runs better on cool mornings than on hot afternoons as cool air is denser and contains more oxygen. You can feed your engine more oxygen by reducing the restriction of the airflow.
