An intercooler mounted on the cylinder head with an intake manifold of an internal combustion engine. The intake manifold and cylinder head are adapted for fastening together for operation with or without the intercooler mounted between the manifold and the cylinder head. The use of a sandwich type intercooler arrangement permits use of standard components of the manifold or engine head with the optional use of the intercooler as a turbocharged engine or without as a naturally aspirated engine.
