Where is the Intake Manifold Located?

[DiCamila]

Intake manifold is located between the throttle body and the engine intake valves. It is called a manifold because after air enters the throttle body, the airflow passage diverges here after being stabilized by the manifold buffer system. The number of diverging passages corresponds to the number of engine cylinders - for example, a four-cylinder engine has four passages, while a five-cylinder engine has five passages, directing air into each cylinder respectively. Here are some details about intake manifolds: The intake manifold must distribute the air-fuel mixture or clean air as evenly as possible to each cylinder. To achieve this, the length of the airflow passages inside the intake manifold should be as equal as possible. To reduce airflow resistance and improve intake efficiency, the inner walls of the intake manifold should be smooth.
