For 1990-2009 cars

The air induction system draws outside air into the combustion chamber. The intake air flows through a forward mounted duct and resonator (silencer) assembly to the air cleaner assembly. The intake air passes through an air filter element into the bore of the throttle body fuel injection unit. The intake air is mixed with fuel in the throttle body fuel injection unit and passed on to the intake manifold. The intake manifold distributes the intake air (air/fuel mixture) to the ports in the cylinder head and the combustion chamber. The air filter element is incorporated into the air cleaner assembly in order to keep dirt from entering the engine.
