what is throttle body

A throttle body is a component of the air intake system in a car that controls the amount of air that flows into the engine. It works by using a butterfly valve to vary the airflow based on the input from the accelerator pedal. In electronically fuel-injected cars, it communicates with the electronic control unit to supply the corresponding amount of fuel needed at the injectors. The throttle body can be found in different areas depending on the vehicle's engine type, and it is connected to the accelerator pedal by a mechanical linkage in older vehicles. Additionally, some car owners add a throttle body spacer to maximize the amount of airflow to the engine, aiming to increase horsepower and fuel economy
