The standard intake component responsible for regulating airflow into the engine of a 5.7L Hemi is typically a 80mm unit. This dimension reflects the diameter of the opening through which air passes before entering the intake manifold.
Correct throttle body sizing is crucial for optimized engine performance. A well-matched intake component ensures adequate airflow across the engine’s operating range, contributing to efficient combustion, improved throttle response, and maximized power output. Historically, engine designs have evolved to accommodate larger intakes to meet the demands of increased horsepower and torque.
