Mercedes-Benz AMG GT C Auxiliary Radiator by CSF (Left or Right). High-performance, all-aluminum drop-in unit featuring CSF B-Tube technology and a black detachable rock guard for dependable cooling.
Working with the factory system, this auxiliary radiator helps control engine coolant temperatures and serves as the heat exchanger for the air-to-water charge-air coolers to reduce IATs and delay heat soak. Its 2-row ~42 mm core offers about double the capacity of the ~26 mm OEM unit, while 6.5 mm multi-louvered fins improve heat dissipation. CNC-machined brackets and OEM-style quick-connects deliver a true drop-in fit for 2018+ AMG GT C and GT R. Sold individually; fits left or right. For maximum cooling performance, consider pairing with CSF’s Front Mount Heat Exchanger (CSF #8088).
