2004 Chevrolet ClassicFACTORY OEM SERVICE PROCEDURE

Air Intake System Description

The air induction system draws outside air through a forward mounted air cleaner. The air cleaner is remotely mounted. The air enters the engine by flowing in through the intake duct into the lower air cleaner, through the air filter, out of the upper air cleaner, through the flex duct, into the air cleaner outlet resonator, and into the throttle body and the intake manifold. The air is then directed into the intake runners, the cylinder head and into the cylinders. A remotely mounted resonator and a resonator mounted on the throttle body help to dampen the noise caused by drawing air into the engine.
