Description
CSF High-Performance Heat Exchanger and Transmission Cooler Module - BMW F9X X3M/X4M is designed to help manage transmission-fluid temperature and reduce the thermal stress created by towing, spirited driving, off-road use, or repeated heavy load. This parent listing begins with CSF part number CSF8331.
As a heat exchanger, it transfers unwanted heat out of the relevant fluid circuit and supports more stable system temperatures. The added cooling capability is useful for towing, off-road use, performance driving, heavy vehicles, warm climates, and modified applications that create additional drivetrain heat.
It is particularly relevant for vehicles used for towing, off-road driving, performance use, heavy loads, or operation in high ambient temperatures.
