Dual Core Radiators

Every Be Cool aluminum dual 1" core crossflow performance radiator contains two oval fluted tubes. The fluted oval tubes "Turbulate" the passing water for maximum exposure to the outer wall of the radiator tube. Be Cool has experimented with dual 1-1/4" and 1-1/2" cores but the thicker radiator made it more difficult to pass air all the way through the radiator and no gains were found. All Be Cool dual core models feature a loose-fin design for maximum cooling.
