An oil temperature reduction of 30 to 40 degrees Fahrenheit can be realized with the installation of our specially designed Oil Cooler Kit. This Oil Cooler Kit allows hot oil to be circulated and cooled outside of the motor through a high efficiency cooler, reducing oil temperature from a typical 225 degrees to an optimum 185 degrees Fahrenheit. Thousands of miles of engine life will be added by keeping a "cool" coating of oil on high-wear engine components such as piston rings, piston skirts, cam bearings, and rod bearings. The Oil Cooler Kit is complete and includes all the necessary adapters, fittings, and hoses you will need for installation. 300ZX Twin Turbos originally come with a smaller oil cooler and will benefit with this larger version. Uses stock hoses and mounting on the Turbo models. Hoses are supplied with the non-turbo kits.
