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

BMW F8X M3/M4/M2 Comp High-Performance Auxiliary Radiator

CSF manufactures the most advanced and efficient radiator in the industry for your F8X M3/M4/M2 Comp. CSF uses innovative tube and fin technologies with industry-leading testing methods to maximize airflow and heat dissipation.

Like the other cooling systems on the F8X the factory auxiliary radiators 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 have pushed the limits of their S55 CSF saw the need and demand. The F8X platform is also almost a decade old with the newest examples being at least 5 years old. Over time the original coolers end up with damaged or clogged fins that greatly reduce their cooling capacity.; CSF designed the coolers to be a true "Drop-in Fit" for easy installation. 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 F8X coolers the CSF units are a significant upgrade. CSF eliminated the OE plastic mounting pod by incorporating it into the modular design that fits both sides. This design improvement increases the size of both the core and tanks. The extra space taken from the mounting pod allowed for a 7% increase in Core Size and an 10% increase in Tank Volume. With a larger 2-row 42mm core cooling efficiency and capacity are drastically increased. The high efficiency core using CSF's Exclusive B-Tube Technology maximizes airflow and heat dissipation. 100% All-Aluminum construction ensures the best performance and durability. The mounting pins and brackets are much stronger and more durable than the OE plastic pod mounting system. In addition the black finish provides extra protection and offers a stealthy look behind the grilles of your F8X. In addition the CSF auxiliary radiators also feature 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.
