CSF’s High-Performance Auxiliary Radiators work in conjunction with the rest of the cooling system to reduce temperatures. They not only help keep temperatures in optimal ranges, prolonging the heat soak threshold, but also can be utilized as the heat exchange medium for the charge cooling system. 

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.

Sold Individually – some applications require 2 auxiliary radiators
