CSF’s ‘Game-Changer’ Front-Mount Heat Exchanger for the F80, F82 and F83 M3/M4. This part is a direct drop-in replacement for the OE heat exchanger, which is paired with the engine’s chargecooler.

CSF’s ultra-high quality, all-aluminium construction and 45-row design offer a dramatic increase in cooling capabilities, and this cooler also includes a rock-guard to protect it from damage. Developed in conjunction with Yost Autosport on its M4 endurance racecar.
