What is a Throttle Body? A throttle body in a car is used to maintain and control how much air is allowed into the engine. You can compare it to a butterfly valve. You can find this between the air cleaner and the intake manifold. It is generally made from aluminum. When the driver puts pressure on the pedal, input data is collected. As more fuel is allowed to enter the engine, better combustion and acceleration power is granted as more air enters in. What happens to your car when the throttle goes bad? .
