What Is A Throttle Body and What Does It Do?

The throttle body is the part of the engine that controls how much air enters the engine cylinders. It's located between the air filter and intake manifold and regulates airflow using a throttle plate. When you press down on the accelerator pedal in your vehicle, this throttle plate opens up to allow more air into the engine, which increases throttle response and power.

The throttle body is typically located on the driver's side of your vehicle's engine compartment. Depending on the make and model of your vehicle, it may be located at the front or back of the engine bay. You can typically identify the throttle body by its large throttle plate and several vacuum ports.

In some vehicles, there is actually more than one throttle body. This is known as a twin throttle setup, or dual throttle bodies, and is common in high-performance engines. The additional throttle bodies provide greater airflow for increased power and throttle response.
