In order to offer a complete cooling solution for the GT R and GT C, CSF is now offering the worldu2019s first High-Performance Auxiliary Radiator to complement our already available Front Mount Heat Exchanger . It is a direct replacement for OEM part number 099-500-54-00 and fits: 18+ Mercedes AMG GT R u2013 190 (Fits Left & Right u2013 2 Per Vehicle) 18+ Mercedes AMG GT C u2013 190 (Fits Left & Right u2013 2 Per Vehicle) 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. Many track enthusiasts have stepped into taking the top-of-the-line AMG roadsters and coupes to the track u2013 where they unfortunately quickly find out about the track debris build-up and possible punctures to their OEM auxiliary radiators, which have little protection against the elements. CSF has included a more durable and higher protection, detachable rock guard to help minimize the build-up of debris, as well as provide further protection against damage and potential leaks of the radiator core. CSFu2019s exclusive Auxiliary Radiators are not only a higher performance, more durable upgrade, but are also a cost competitive alternative to replacing OEM plastic tank auxiliary radiators.
