( CSF #8187 )

As we move into trade show season, with some high-level projects nearing completion, CSF is shifting our focus to new product development. After the launch of our #1 selling Front Mount Heat Exchanger for W205 Mercedes AMG, we saw a lot of demand for more Mercedes-Benz products, so we are planning an entire lineup of new MB cooling systems. 

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.

CSF’s New W205 AMG Auxiliary Radiators (CSF #8187)

Coming off the industry-leading Front Mount Heat Exchanger for W205 AMG, we’ve decided to start off our expansion of our High-Performance Mercedes-Benz cooling systems with complementary Auxiliary Radiators for the W205 AMG.

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.
