Your Mazda 6 utilizes a fuel injection system to supply fuel to your engine. The throttle body controls the airflow into your engine, and operates depending on the amount of depression on the throttle pedal. With an increased amount of air flowing into the engine, there is an increased amount of fuel injected, thus allowing for more power.
