CSF began designing the Heat Exchanger for the X3M/X4M using all the experience and data gathered from the entire G8X Cooling Suite. The first hurdle in designing a Front Mount Heat Exchanger for these vehicles was the space constraints. The X3M and X4M use a different transmission oil cooler than the G8X models that restricted increasing the size of the Heat Exchanger due to the mounting cradle. After testing a few smaller core options, CSF determined it made more sense to combine the Heat Exchanger with a Transmission Cooler Upgrade to maximize size and performance.

By combining the Heat Exchanger and Transmission Cooler into a full cooling module, CSF was able to run the same size core as the G8X Heat Exchanger. The Auto Transmission Cooler uses the same dual core design as the G8X Transmission Cooler which is fitted to the new Heat Exchanger. This creates a cooling module that comes as a single unit. The combination not only solves two cooling issues for the X3M and X4M, but also lowers costs which are passed along to the customer.
