For more information, visit www.P65warnings.ca.gov.The high-revving S65 engine in the E9X M3 generates significant heat during track sessions or aggressive street driving, often taxing the factory cooling system. The CSF 7059 replaces the standard radiator with a high-performance all-aluminum unit designed to maintain lower outlet temperatures under load. A triple-pass flow structure forces coolant across the core three times before exiting, while CSF's exclusive B-Tube technology increases heat transfer surface area by approximately 15% over conventional oval tubes.
