By dramatically lowering the temperature of the oil–and your water temp accordingly–Twin Air’s patented oil cooler can keep your rides–and your engine–at peak performance longer. Twin Air’s solution is a revolutionary improvement. Unlike traditional coolant-based approaches that tap into the water cooling system, Twin Air’s design is the first air-cooled driven solution. From a mounting panel behind the radiator, flexible hoses circulate oil to a unique, tubular cooling grill designed to maximize heat exchange. The Twin Air Oil Cooler kit includes everything you need-heat exchanger, mounting hardware, oil filter cap, hoses, clamps and step-by-step instructions.
