The air induction system consists of throttle body and intake manifold. Air for combustion enters throttle body and is distributed to each cylinder through intake manifold.

Throttle body contains special distribution skirt below each injector valve to improve fuel distribution. Airflow rate is controlled by throttle valves which are connected to accelerator linkage. Idle speed is determined by position of throttle valves and is controlled by ISC.
