FLUIDYNE® “Cooler-Coolers” have the same features found in FLUIDYNE®’s High Performance radiators, such as all-aluminum construction with a CAB-brazed core (no epoxy) for outstanding durability. The design elements of these “Cooler-Coolers,” such as the fin design and core configuration are used by many of the top up-fitters. These are Factory-Fit replacements which utilize the stock brackets for simple bolt-on installation.
