CSF BMW F8X Auxiliary Radiators w/ Rock Guards
Improve the cooling capability and durability of your BMW F8X chassis with CSF High Performance Auxiliary Radiators.
Designed for the BMW F80 M3, F82/F83 M4, and F87 M2 Competition, these upgraded auxiliary radiators replace the weaker OEM plastic mounting design with a stronger all-aluminum construction built for demanding street, track, and high-performance applications.
CSF redesigned the factory layout by integrating the mounting system directly into the radiator assembly, allowing for increased core size, larger tanks, and improved cooling efficiency.
The included bolt-on rock guards provide additional protection against road debris, helping prevent costly cooler damage during aggressive driving.
