CSF Charge-Air Cooler Pair for BMW G90 / G99 M5 (2025+)

Replace both G90/G99 M5 liquid-to-air charge coolers with the CSF pair matched to the hybrid S68 installation. Minor fitting modifications are required: the resting pins need shaving and the air-balancing tube needs the manufacturer’s specified trimming.
