BMW G8X M3/M4/M2 High-Performance Auxiliary Radiator
Overview
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.
Details
CSF manufactures the most advanced and efficient auxiliary radiator in the industry for your BMW G8X M3/M4/M2. CSF uses innovative tube and fin technologies with industry-leading testing methods to maximize airflow and heat dissipation.
