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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDesign \u0026amp; Engineering\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCSF 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOEM vs CSF\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCompared to the OEM 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.\u003c\/p\u003e\n\u003cp\u003eWith many motorsports teams and race enthusiasts now pushing over 700 horsepower, the B58 is seeing coolant temperatures well above normal. Once temperatures pass a safe limit the B58 will go into limp mode. Needless to say this can ruin a race, track session, or your overall driving fun in general. CSF is here to keep your B58 running at peak performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eConstruction\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e100% 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.\u003c\/p\u003e\n\u003cp\u003eCSF 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eF87 M2 N55 Cooling System\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe F87 M2 Competition uses the same cooling system as the F8X M3 and M4, the N55 version has a completely different setup.
