The CSF 31mm aluminum core is a big improvement over the factory core. A thicker core and increased fluid capacity drastically improves the amount of heat the system can absorb and dissipate. CSF's Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible cooling performance.
