What is the primary function of the intake manifold?

The primary function of the intake manifold is to distribute clean air evenly to each cylinder of the engine. This component is crucial because an even distribution of air ensures that each cylinder receives the necessary airflow needed for optimal combustion. When the air enters the engine, it mixes with fuel, and this mixture is ignited to create the combustion that powers the vehicle.

By maintaining a balanced airflow, the intake manifold helps to improve engine performance, efficiency, and power output. Any discrepancies in air distribution can lead to one or several cylinders running either too rich or too lean, negatively impacting combustion efficiency and engine performance. Therefore, the design and function of the intake manifold play a critical role in achieving the desired engine performance and fuel efficiency.
