CSF BMW G8X M3/M4/M2 High-Performance Auxiliary Radiator - Single Radiator

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.This Part Fits: Year Make Model Submodel 2023-2024 BMW M2 Base 2021-2024 BMW M3 Base 2021-2024 BMW M3 Competition 2022-2024 BMW M3 Competition xDrive 2024 BMW M3 CS 2021-2024 BMW M4 Base 2021-2024 BMW M4 Competition 2021-2024 BMW M4 Competition xDrive 2023 BMW M4 CSL
