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.

CSF’s All-Aluminum High-Performance Heat Exchanger is larger and cools the water more efficiently than the OEM plastic/aluminum unit thus helping deliver cooler and denser air through the charge air cooling system increasing power capabilities. In its recent testing, Regal Autosport saw significant performance improvements consisting of up to a 68% reduction in IATs (intake air temperatures) and a 400% improvement in heat soak reduction when compared to stock.  

As with all of CSF’s high-performance products, the same degree of engineering that has gone into the effectiveness of each product has gone into other aspects of its quality – from its hand-polished mirror finish to extensive testing and perfect “drop-in” fitment that the CSF name prides itself upon.
