CSF 18+ Mercedes AMG GT R/ GT C Auxiliary Radiator- Fits Left and Right - Sold Individually

When you're pushing your Mercedes-Benz AMG GT R or GT C hard, keeping temperatures in check is crucial, especially for the turbochargers. This high-performance auxiliary radiator from CSF is designed to work with your existing cooling system to help manage those heat loads. It's not just about the engine coolant; these auxiliary radiators are also a key part of the air-to-water charge-air cooling system, directly impacting intake air temperatures and, by extension, engine performance.

CSF builds these radiators with a focus on maximizing heat exchange. They feature a 2-row, 42mm core with ultra-efficient 6.5mm tall fins and a multi-louvered design to increase surface area contact for better airflow. The all-aluminum, TIG-welded construction is solid, and CSF even adds a detachable rock guard to protect the core from road debris, something the factory units lack. This unit offers approximately double the cooling capacity of the OEM radiator, which helps extend the heat soak threshold and keeps temperatures in optimal ranges for longer periods. CSF also offers a hand-polished mirror finish on this unit, giving it a clean look behind the grille.

This auxiliary radiator is designed as a direct, drop-in fit, meaning it uses CNC machined mounting brackets and OEM-style quick-connect fittings, so no modifications are needed for installation. CSF recommends replacing both the left and right auxiliary radiators if your vehicle came with two from the factory, and for the ultimate cooling setup, they suggest pairing this with their front mount heat exchanger. Each radiator is individually leak and pressure tested before it leaves the factory, and it comes with a 2-year limited warranty.
