Mishimoto Performance Heat Exchanger, BMW F8X M

Improve the cooling capacity on your 2015-2020 BMW M3 or M4 with the Mishimoto Performance Heat Exchanger. Air-to-water intercooling is the means of more efficient heat transfer from the charged air, but it now requires an additional heat exchanger mounted to the front of the vehicle in order to dissipate the transferred heat. The S55 powering the F8X generation of the M's packs quite a punch and while the BMW engineers laid a solid foundation for dissipating the heat from the intercooling system, but Mishimoto saw some room to improve. They started by eliminating any bits of plastic from the design, and replacing the end tanks, and ports with durable aluminum. Mishimoto kept the dual-pass flow through the core for maximum cooling properties, while expanding the core into the available space. Mishimoto's new design features a 42 mm thick core while extending the height by 150 mm totaling in a 60-percent increase in core volume and adding 180-percent to the external fin surface area. T
