The CSF 8215 upgrades the front heat exchanger in the S58 BMW M2, M3 and M4 charge-air cooling system. Its two-row, 42mm B-Tube core uses the current 2026 5mm Track-Spec fin design.
This is a low-temperature charge-cooling component, rather than a replacement for the engine’s main radiator. The mounting provisions also account for the different manual and automatic transmission layouts behind the front cooling pack.

Product FAQs
Does this replace the engine coolant radiator?
No. It is the front heat exchanger for the charge-cooling circuit.
Is it compatible with manual and automatic cars?
CSF lists both configurations. Manual cars use upper and lower guards; the automatic layout uses the upper guard and transmission-cooler mounting kit.
What other cooler works with the automatic layout?
The CSF 8221 ZF8 transmission cooler is designed for the original heat exchanger or the CSF 8215. It is sold separately.
