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 – 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.

CSF’s 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.
