DeutschTuning proudly offers CSF C63/63S W205 AMG Auxiliary Radiators. It’s common knowledge that AMG vehicles suffer from heat soak issues, especially those in warmer climates – Our next phase will eliminate this, as we continue to upgrade the radiator heat exchangers for all of the most popular AMG platforms. The High-Performance All-Aluminum Auxiliary Radiators work in conjunction with the rest of the cooling system to reduce temperatures throughout. This is critical as the Auxiliary Radiators not only help keep engine water temperatures lower, but also are utilized as the heat exchange medium in the air-to-water charge-air coolers for the turbocharger system to reduce intake air temperatures (IATs). Overall, the Auxiliary Radiators larger capacity prolongs the heat soak threshold and assists in keeping temperatures in optimal ranges. 2 Required sold a single radiator.
