Description of 12629992 Injection Throttle Assembly Silverado
A throttle body is a butterfly valve located between the air intake filter and the intake manifold. As the gas pedal is pushed down by driver, the valve opens, allowing air to enter the engine. As more air flows into the engine, it injects more fuel, thus allowing for more power. A properly sized throttle body will provide sufficient airflow and velocity for good engine power and throttle response.
