Abstract: An exemplary intake manifold may include an upper manifold configured to receive fresh air, an EGR tube configured to introduce exhaust gas into the upper manifold to be mixed with the fresh air, and a lower manifold configured to distribute the mixture of the fresh air and the exhaust gas cylinders of the internal combustion engine. The upper manifold may include an upper shell and a lower shell that may cooperate to define at least one channel in which at least a portion of the EGR tube may be secured.
