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. By ensuring an even distribution of this mixture, the intake manifold helps optimize engine performance and efficiency. Made from materials like aluminum or plastic, the design of the intake manifold can vary based on the engine type. It often includes features such as runners and plenum chambers, which help manage airflow. Proper functioning of the intake manifold is essential for the overall performance of the engine and its related systems, including the throttle body and cylinders.
