A throttle body in a car is an essential component of the engine's air intake system. It acts as a gatekeeper, controlling the amount of air that enters the engine. The primary function of a throttle body is to regulate the engine's air intake, ensuring the right amount of air is mixed with fuel for combustion. By controlling the throttle body, the driver can control the speed and power of the vehicle.

The throttle body consists of a butterfly valve that opens and closes to control airflow. When the driver accelerates, the valve opens wider, allowing more air to enter the engine, resulting in increased power. Conversely, when the driver decelerates or comes to a stop, the valve closes to restrict the airflow. This action helps maintain a smooth idle and reduces fuel consumption. The throttle body is usually controlled electronically, allowing for more precise throttle response and improved fuel efficiency.
