BMW F82 - Auxiliary Coolant Radiator — Overview

This is an auxiliary coolant radiator for the F82 M4 cooling system. On these cars, the side radiators do a lot of the work once you start leaning on the S55, especially in hot weather, traffic, or repeated pulls. If your original unit is bent, leaking, or packed with debris, replacing it is the straightforward fix instead of gambling on a marginal cooling system.

I’d pick this when you need a stock-style replacement and just want the car cooling properly again. It makes sense for a street car or lightly tracked F82 where OEM-style fitment matters more than chasing a bigger custom setup. As with any radiator job on an S55 car, check the surrounding hoses, ducting, and mounting points while you’re in there because that’s usually where install headaches show up.
