The air induction system provides contaminant and sound filtration of the outside air as it is drawn into the engine. A remotely mounted air cleaner prevents contaminants in the air from entering the engine. The filtered air is routed into a lower and upper air cleaner assembly. The air then enters the engine by flowing through the throttle body, into the intake manifold, through the cylinder head intake ports, and into the cylinders.
