Derale Performance 13731 6-Pass Tube & Fin Replacement Cooler Core 11/32" Barb Inlets

The Derale Performance 13731 is a direct replacement 6-pass tube and fin cooler core designed specifically for Derale's Econo-Cool remote oil cooler systems. Built with 1/2" copper tubing expanded into aluminum cooling fins, this core delivers efficient heat transfer in a compact, durable package.

The 6-pass cooler design maximizes fluid contact time within the core, improving thermal efficiency and helping to reduce fluid temperatures more effectively than lower-pass alternatives. Extruded plastic cooling fin guards protect the delicate aluminum fins during handling and installation. The entire assembly is finished in a durable black powder coat for long-lasting corrosion resistance.
