About CSF radiators

CSF build all-aluminium radiators that drop into the factory location and accept the original hoses, brackets, shroud and condenser, so the extra cooling comes without fabrication.

The gain comes from the core rather than from size alone: a dual row design with CSF's B-Tube construction and a high density louvred fin, which puts more surface area in front of the same airflow. On a car that climbs in temperature under load, towing or on track, that is what holds it steady.
