What is a Throttle Body?
The throttle body is a component of the engine that controls the amount of air that enters the engine. It is located between the air filter and the intake manifold. The throttle body is controlled by the accelerator pedal. When you press on the accelerator pedal, the throttle body opens, allowing more air to enter the engine. This causes the engine to speed up.
