Description And Operation
The intercooler is built into the intake manifold. Heat is removed from the air entering the intercooler by low-temperature water that is circulated within by a dedicated cooling system through the coolant inlet and outlet ports (1).
The intercooler is inside the intake manifold "box" and is fastened to the manifold with screws.
The airflow from the turbocharger is controlled by the throttle body and enters the bottom of the intake manifold. Once inside the manifold, the air gives off heat as it passes through the intercooler plates, which are maintained at a lower temperature by the coolant circulating within. This lower temperature air mixes with the idling engine oil vapor inlet (1) and exits from the manifold to enter the cylinder head intake ports.
