The Derale 15865 is a 25 row Hyper-Cool remote mount cooler that pairs an all-aluminum oven-brazed stack plate core with an 8 inch Tornado fan and aluminum shroud. Mounting the fan on the cooler lets it cool effectively in a remote location away from the airstream. The -10AN inlets use a 7/8-14 O-ring to -10AN male fitting, and two -10AN to 1/2 inch hose barb adapters are included. It is designed for engine oil and also handles heavy-duty transmission or fuel cooling.
