An industry-leading reputation and overwhelming success with BMW cooling has made CSF the #1 cooling choice for the G8X M3/M4/M2. CSF is leading the way in BMW G8X (S58) Cooling and adding another product to the Power Cooling Package. Now CSF is pleased to announce the release of the BMW G8X M3/M4/M2 High-Performance Auxiliary Radiators.

The new CSF Auxiliary Radiators are a great addition to the massively successful G8X Cooling Suite. Like the other cooling systems on the G8X, 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 S58, CSF is here to keep them cool.

CSF designed the coolers to be a true “Drop-in Fit” for easy installation fitting both left and right sides. Each cooler mounts in the factory location and uses the OEM quick connections. The High-Performance Auxiliary Radiators work in conjunction with the rest of the cooling system to reduce temperatures. They not only help keep temperatures in optimal ranges, but prolong the heat soak threshold. There’s nothing worse than having your track session cut short because you need to do a cooldown lap.

Compared to the OEM G8X coolers, the CSF units are a significant upgrade. The TIG welded aluminum tanks are much larger than the OE plastic tanks offering superior strength and fluid volume. A larger 2-row 42mm core increases cooling efficiency and capacity. This high efficiency core uses CSF’s Exclusive B-Tube Technology and latest 5mm fin technology, maximizing airflow and heat dissipation. These 5mm fins significantly increase the heat exchange surface area improving overall cooling efficiency and recovery while still maintaining good airflow.

100% All-Aluminum construction ensures the best performance and durability. The mounting
