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. Each core is 26% larger than the original featuring 2-Row 42mm aluminum core. This both increases the fluid capacity of the radiator, and improves the core's ability to dissipate heat. The use of CSF's 5mm fins also allowed for an additional cooling tube and fin row.
