GReddy GREX Oil Cooler Kits help prolong the life of your oil and in turn your internal engine components. Hard driving causes higher engine temperatures. GReddy GREX oil coolers are an excellent addition, and are especially effective in harsh driving environments. By using a similar inner fin core design as our famous intercoolers, we are able to increase oil capacity, decrease oil temperatures, and extend engine and oil life. Our systems also offer an internal (or external) thermostat (opening range 71 80C) to allow for quick engine warm up. The efficient core and durable steel braided lines ensure good flow and a leak free installation.
