AMG GT Platform • Track-Proven Cooling Upgrade

CSF 8187 Auxiliary Radiators for Mercedes-AMG GT / GTS / GTC / GTR

High-capacity all-aluminum auxiliary radiators engineered to control heat soak, stabilize oil and coolant temperatures, and maintain consistent power on the M178-powered AMG GT platform.

The CSF 8187 Auxiliary Radiators are a critical cooling upgrade for Mercedes-AMG GT owners pushing their cars beyond factory limits. Whether you’re experiencing rising temperatures on track, during aggressive canyon driving, or on tuned setups, these radiators dramatically improve heat rejection where the OEM units fall short.

Built specifically for the M178 4.0L BiTurbo V8, the CSF 8187 increases coolant volume, flow efficiency, and thermal stability — allowing your AMG GT to deliver consistent performance lap after lap.
