An exhaust gas recirculation (EGR) system that utilizes an insulated separation wall that separates the hot, humid EGR gas duct from the cool, dry inlet air duct in the upstream proximity of the compressor inlet of the associated turbocharger compressor. This insulated separation wall inhibits the condensation of water droplets and the formation of ice particles near the mixing point of the EGR gases and inlet air in the upstream proximity of the compressor inlet, such that the turbocharger compressor wheel, blades, and other components are not subsequently damaged by the condensed water droplets or formed ice particles. The added insulation in this cold sink area essentially thermally isolates the hot, humid EGR gas flow from the cool, dry inlet air flow until the actual mixing point of the flows.
