Fits 2015-2020 BMW M2 Competition, M3, and M4 (S55 engine).

Improve the thermal efficiency of your S55-powered BMW with the Mishimoto Performance Heat Exchanger. In the F8X chassis, the air-to-water intercooling system relies on a front-mounted heat exchanger to dissipate heat from the charge air.
