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.

CSF manufactures the most advanced and efficient auxiliary radiator in the industry for your BMW G8X M3/M4/M2. CSF uses innovative tube.

The CSF #8321 Cooling product is designed to be a "Drop-In Fit" application. The product will install in the OEM Location with no modifications necessary unless otherwise noted or instructions are included in the product package. Please see the manufacturer repair manual for standard installation instructions..
