Further Information

CSF delivers championship-grade cooling for your BMW F2X/F3X with an all-aluminum high-performance radiator engineered for street and track duty. Designed to keep your engine running at optimal temperatures, this 2-Row core radiator is a must-have for high horsepower builds and motorsports applications demanding superior thermal management.

The radiator features CSF's exclusive B-Tube Technology, a specially engineered tube design that is brazed rather than welded, creating approximately 15% more heat transfer surface area than conventional O-tubes while using thinner, lighter aluminum. Multi-louvered fins with 6.5mm fin height are precision-aligned and wind-tunnel tested to maximize airflow and heat rejection efficiency.
