The intake manifold is a crucial component in an internal combustion engine. It is responsible for directing the air-fuel mixture from the throttle body to the engine's cylinders. The design of the intake manifold can significantly affect engine performance, efficiency, and power output. Typically made from materials like aluminum or plastic, the intake manifold is shaped to optimize airflow. It often includes features such as runners and plenum chambers, which help distribute the mixture evenly to each cylinder. Proper functioning of the intake manifold is essential for the overall performance of the engine and its related systems, such as the fuel injectors and throttle body.
