The CSF radiator features a 1-Row 31mm aluminum core that not only increases the fluid capacity of the radiator, but also improves the cores ability to dissipate heat. CSF went through several different prototypes using cores of varying thicknesses. The 31mm core was found to be the best balance of performance and fitment. This sizing allows for use of an OE style clutch pull fan or an aftermarket electric push fan. CSF's Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. With nearly double the number of cooling fins and tubes, the CSF Radiator will outperform the OEM unit by a significant margin. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance. The radiator mounts in the factory location and requires no modifications or cutting.
