Gplus Oil Cooler Kits help prolong the life of your oil and your internal engine components. Hard driving causes higher engine temperatures,Gplus oil coolers are an excellent addition, and are especially effective in harsh driving environments. By using a similar inner-fin core design as the famous oil coolers, we are able to increase oil capacity, decrease oil temperatures, and extend engine and oil coolers life. Our systems also offer an internal (or external) thermostat (opening range 80℃ (176 F)) to allow for quick engine warm up. The efficient core and durable steel-braided or nylon steel-braided lines ensure good flow and a leak free installation. Every cooler is pressure checked to 175 psi. Our periodic samples are burst tested to 350 psi.
