Koyorad builds its performance radiators with Nocolok furnace brazing and hand welded Heliarc joints, giving each core the strength to handle sustained track use without the factory unit's compromises. This all aluminium core is engineered as a direct upgrade for the S55B30T0 twin-turbo straight six, keeping coolant temperatures stable when the heat really builds up. SKU VH423704.
This listing covers the BMW M3 (F80), M4 (F82/F83) and M2 Competition (F87), across manual and M-DCT transmissions. It's a direct bolt-in replacement using the factory mounting points, fan shroud, and hose connections, with no modifications required.
Vehicle compatibility, OEM part numbers, and fitment notes are provided in the tabs above. Please confirm your vehicle's model year and transmission before ordering.
