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's Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. The 6.5mm super-efficient multi-louvered fins maximize airflow through the core for the best possible performance. In addition, CSF was able to fit 2 additional cooling tubes and rows of fins. The combination of TIG-Welded 100% All Aluminum construction and dual core straps increase the overall strength of the radiator. This improves durability and longevity so you can be confident it will hold up to hard driving conditions. Additionally, the satin black finish gives the radiator a clean OEM look and both radiators are a true Plug-and-Play "Drop-in Fit" application.
