CSF Cooler

Fits: CSF BMW G9X M5 Charge-Air-Coolers (2025+)

The M5 has long been the king of full size sport sedans and the new G9X M5 is no exception. People can complain about how big and heavy it has gotten. At the end of the day, it is seriously quick, handles incredibly well, and is dripping in luxury. One of the limiting factors in making power on the S68 engine are the fragile factory charge air coolers. CSF quickly resolved that issue by revising the S63/S68 Charge-Air-Coolers for the F9X M5/M8/X5M/X6M for the new G90/G99 M5.
