Component Descriptions, Ls intake manifold with throttle body

The intake manifold is more than just a conduit. Crucial components include runners, plenums, and the throttle body itself. Runners direct the airflow from the throttle body to each cylinder. The plenum acts as a collection point for the air, smoothing the airflow and preventing turbulence. The throttle body controls the amount of air entering the engine, acting as a gatekeeper for the entire system.

The throttle plate directly regulates airflow, reacting to driver input.

Airflow Path

Understanding the airflow path through the intake system is paramount. Air enters the throttle body, its flow controlled by the throttle plate. From there, it flows through the runners, directing air to each individual cylinder. A well-designed intake manifold minimizes turbulence and ensures uniform air distribution, leading to optimized engine performance.
