Abstract
An internal combustion engine includes an engine block defining a plurality of cylinders. A cylinder head casting is mounted to the engine block. The cylinder head casting defines intake ports and exhaust ports communicating with the plurality of cylinders. The cylinder head casting defines an air passage in connection with the intake ports and includes elongated extruded cooling elements defining liquid coolant passages integrated into the cylinder head casting within the air passage for cooling intake air passing through the air passage.
