The multi-row aluminum tube-and-fin architecture drastically increases fluid contact surface area and convective heat dissipation. Paired with a tailored aluminum fan shroud and dedicated electric puller fan, it forces consistent volumetric airflow across the entire fin matrix regardless of engine RPM.
