F87 M2 (N55) / F3X 340i/440i / F2X M240i High-Performance Auxiliary Radiator

100% All-Aluminum construction ensures the best performance and durability. The integrated mounting frame is much stronger and more durable than the OE plastic pod mounting system. In addition, the black finish provides extra protection and corrosion resistance. CSF auxiliary radiators offer even more durability with the integrated bolt on rock guards to keep the coolers safe. You've no doubt heard horror stories about OEM coolers getting punctured and spilling fluids all over the road or track. Now you can feel more confident that your cooling system is safer from road debris.
