CSF's high-performance front-mount heat exchanger for BMW G8X M3/M4 uses a 2-row, 42mm core with exclusive B-Tube technology to reduce intake air temperatures and speed heat soak recovery. It improves airflow to the cooling system, fits as a plug-and-play drop-in, and ships with upper and lower Black Rock Guards and transmission cooler mounting hardware for ZF8-equipped cars.
