An integrated tuned air induction system for an internal combustion engine comprises an air intake leading to an air filter compartment. The air filter compartment leads to a tube that extends horizontally past a bank of cylinders that is served by the system. The tube leads to a tubular extension piece that creates a 180 degree turn. After this turn, the airflow passes through an air body containing a valve that controls the induction airflow. After the air body, the airflow passes to a plenum zone that lies parallel to the first tube. Spiral runners arranged transversely to the length of the plenum zone communicate the plenum zone to the intake of each cylinder in the bank. The first tube, the runners, and the plenum zone are formed by a single plastic part. The air filter compartment is defined by an end wall of this part and a removable cover. An integral wall of the part serves to mount the part on the engine while providing support for the runners. The air body has slip fit sealed joints via which it connects into the system.

An induction air circuit for a multi-cylinder internal combustion engine comprising an air intake leading to a first tube that runs parallel to the engine past a bank of cylinders that is served by the induction air circuit, a second tube that creates approximately a 180 degree turn in the induction airflow after the airflow has passed through the first tube, an air body that is located after the second tube and comprises a valve for controlling the airflow, a plenum zone that lies parallel to said first tube and is located after said air body, said plenum zone passing said bank of cylinders, and spiral runners that are arranged transversely to the length of said plenum zone, each runner extending from said plenum zone to a corresponding cylinder, wherein said runners, said plenum zone, and said first tube are a single plastic part, and said first tube and said plenum zone share respective wall portions of said runners as they pass said runners.
