Flex-A-Lite Advanced Engine Oil Coolers are designed to provide maximum cooling to demanding engines under the harshest conditions. These coolers are made entirely of aluminum and feature turbulized fins inserted into the internal cooling plates as well as louvered fins for maximum heat transfer. They can provide up to 4 times the heat displacement compared to typical budget coolers, all while minimizing oil pressure drop. Each cooler comes complete with a set of interchangeable -8AN, -10AN and -12AN hose end O-ring fittings to fit most modern engine applications.
