CSF Mercedes Benz E63 / CLS 63 M157 High Performance All Aluminum Auxiliary Radiators

Mercedes AMG M157 / M278 / M133 High-Performance Auxiliary Radiator

CSF manufactures the most advanced and efficient radiator in the industry for your AMG. CSF uses innovative tube and fin technologies with industry-leading testing methods to maximize airflow and heat dissipation.

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. The included, detachable rock guard offers protection against the build-up of debris, as well as possible core punctures - unlike the OEM auxiliary radiators, which have little protection against the elements. CSF recommends purchasing two Auxiliary Radiators to replace both left and right OEM units (for vehicles with two from the factory). For maximum cooling performance, we advise installing in conjunction with the Front Mount Heat Exchanger (CSF #8197).
