An industry-leading reputation and overwhelming success with BMW cooling has made CSF the #1 cooling choice for the F87 M2 (N55), F3X 340i/440i, and F2X M240i/M140i.
The new CSF Auxiliary Radiators are a great addition to the popular F87 (N55) & F3X/F2X Cooling Suites. Like the other cooling systems on these BMWs, the aux rads do a pretty good job in stock form. However, once you start adding a lot of power and pushing the car in aggressive driving conditions, the factory systems start to show its limitations. As more and more owners keep pushing the limits of their M2s and Gen 1 B58s, CSF is here to keep them cool.
