Don’t be fooled by other high-performance aftermarket options that utilize the OEM plastic rock guard. The OEM rock guard’s vertical channel design is specifically designed to only work with the tube spacing found on the OEM core. When the OEM rock guard is installed on an aftermarket radiator, it actually blocks a significant amount of surface area. Obviously this is detrimental to the intended performance. During CSF’s own R&D phase, CSF analyzed both the OEM and other aftermarket offerings and decided to go the extra mile. CSF redesigned the included rock guard to allow maximum flow to the radiator core, while still offering ample protection from small rocks and road debris – all proven on CSF’s in-house wind tunnel.

CSF’s new Auxiliary Radiator fits both the left and right side of the vehicle as a drop-in fit. Thus requiring no modifications to install. Each features CNC machined mounting brackets and OEM style “Quick Connect” inlet/outlet connections. This makes for a true plug-and-play installation that does not interfere with aftermarket performance aero modifications.
