WARNING: This product can expose you to chemicals that are known to the State of California to cause cancer, birth defects or other reproductive harm. For more information, visit www.P65warnings.ca.gov.The factory radiator in the BMW F2X and F3X chassis can struggle to maintain stable operating temperatures during track use or in high-horsepower street builds. The CSF 7081 replaces the failure-prone plastic end tanks of the original unit with a 100% TIG-welded all-aluminum construction. CSF's exclusive B-Tube technology increases the heat transfer surface area by approximately 15% compared to standard oval tubes, providing the efficiency of two smaller tubes within the same physical space.
