The ARC Oil Cooler Kits help prolong the life of your oil and in turn your internal engine components. Hard driving causes higher engine temperatures. ARC Oil Cooler Kits are an excellent addition, and are especially effective in harsh driving environments. With the ARC Oil Cooler Kit unit we are able to increase oil capacity, decrease oil temperatures, and extend engine and oil life. The efficient core and durable steel-braided lines ensure good flow and a leak free installation.
