Again, the intercooler is completely separate from the turbo, a "radiator" that is mounted in the path of the charged air coming out of the turbo to cool it before entering the throttle body, intake manifold, and, untimately, the cylinder. The cooler air results in more efficient combustion, thereby increasing performance. Cooling the turbo (either using water [coolant] or oil) and intercooling are *completely* different. -Doug
