What is the purpose of the intake manifold?

The purpose of the intake manifold is primarily to distribute the air-fuel mixture to the engine cylinders evenly. This ensures that each cylinder receives a similar amount of air and fuel, which is crucial for optimal combustion and engine performance. An even distribution helps to maintain engine efficiency, power output, and reduces the possibility of knocking or misfires that could occur if one cylinder received more or less mixture than others.

The intake manifold also plays a role in the tuning of the engine, as its design can affect flow characteristics and engine responsiveness. By ensuring that the air-fuel mixture is correctly distributed to each cylinder, the intake manifold contributes significantly to the overall functioning and efficiency of the engine.
