CSF BMW F8X M3/M4/M2C Auxiliary Radiators w/ Rock Guards (Sold Individually - Fits Left and Right

The CSF High-Performance Auxiliary Radiators w/ Rock Guards for the BMW F8X M3/M4/M2 Competition deliver a serious cooling upgrade and added protection for both street and track-driven cars. Sold individually and designed to fit either the left or right side, these radiators are a major improvement over the weak OEM units. CSF eliminated the fragile OE plastic mounting pod and replaced it with an all-aluminum modular design that increases both core and tank size.

The larger 2-row, 42mm core provides a 7% increase in core size and 10% increase in tank volume, drastically improving cooling capacity and efficiency. Built with CSF’s exclusive B-Tube Technology, these radiators maximize airflow and heat dissipation, all while being stronger and more durable than the factory units. Each radiator comes with an integrated bolt-on rock guard, offering essential protection from debris — perfect for performance builds running aggressive aero or open-face grilles. Finished in stealthy black for added durability and clean aesthetics.
