For more information, visit www.P65warnings.ca.gov.The factory plastic end tanks on MK4 chassis radiators are prone to fatigue and leaking after years of heat cycles and vibration. The CSF 7025 replaces the failure-prone OEM unit with a 100% TIG-welded all-aluminum construction designed for both high-horsepower street builds and track use. CSF's exclusive B-Tube technology increases the heat transfer surface area by approximately 15% over conventional oval tubes, providing the efficiency of two smaller tubes within the same physical space.
