The CSF Intercooler Heat Exchanger features a 1-Row 31mm aluminum core with CSF's Exclusive B-Tube Technology. The B-Tube design increases the heat transfer by approximately 15% over regular oval welded tubes. With approximately 32% more cooling tubes & fins, 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 and airflow to the radiator behind it. The heat exchanger mounts in the factory location and requires no modifications or cutting.
