The CSF radiators feature the latest 5mm multi-louvered fins. These fins significantly increase the heat exchange surface area improving overall cooling efficiency and recovery while still maintaining good airflow. The core is 16% larger than the original GM OE radiator. This core volume difference comes from the thicker 2-Row 42mm aluminum core. This both increases the fluid capacity of the radiator, and improves the core's ability to dissipate heat.
