Fits: 2021–2023 BMW M4 2021–2023 BMW M3 CSF8215RadiatorsWhile in stock form, the G8X?s factory cooling system does a decent job keeping up with the cooling demands. While this was true of the car in factory spec, those results changed when the cars were modified and started pushing more power.As with most performance vehicles, power adders were some of the first products to be released for the new G8X platform. Bolt-on upgrades, software tunes, and upgraded turbos are all great for speed, but start to create heat issues. Any time you add power to your car, you naturally increase the amount of heat the engine produces.The CSF Heat Exchanger features a 2-Row (vs OEM single row) Core that is 42mm thick with CSF?s Exclusive B-Tube Technology. Increasing the size of the core and end tanks adds to the overall volume of the system which helps absorb more heat. The more efficient core not only helps dissipate more heat from the system, but also provides better airflow into the radiator that sits behind the heat exchanger. For vehicles equipped with the ZF8 Automatic Transmission, the heat exchanger core specifications were design concurrently with CSF?s new Race-Spec Dual Core Transmission Oil Cooler (CSF #8221).The two included Black Rock Guards offer full protection for the heat exchanger (above and below the crash bar), especially when paired with aftermarket "open face" race style grilles. These grilles have become quite popular for performance and aesthetics, and keeping your heat exchanger safe from debris is very important.With well over 100 track hours worth of testing and thousands of miles on the road, you can be assured that the CSF?s new High-Performance Front Mount Heat Exchanger has been thoroughly tested and vetted.
