CSF 93-01 Mercedes-Benz R129 SL600/SL70 / SL72 / SL73 OEM+ Performance All-Aluminum Radiator

The RENNTech by CSF radiator features 6.5mm multi-louvered fins. These fins significantly increase the heat exchange surface area, improving overall cooling efficiency and recovery while improving airflow over the 6mm OE fins. CSF was able to maintain the same tube and fin row count as the OE unit with a larger fin height due to the shorter but more efficient 2-Row B-Tubes. These features improve the core's ability to dissipate heat while making it more structurally robust. CSF's Exclusive B-Tube Technology increases 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 performance.
