For 1990-2009 cars

The air induction system provides contaminant and sound filtration of the outside air as the air 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 forward mounted resonator by an intermediate air duct assembly. The resonator aids in reducing induction noise. 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.
