The Nissan / Infiniti 3.5 and 3.7 liter engines run hot. In high performance conditions, the 3.7 can go into a reduced power mode due to overheating oil. An oil temperature reduction of 30 to 40 degrees Fahrenheit can be realized with the installation of our specially designed Oil Cooler Kits, ending the oil overheating condition. These Oil Cooler Kits allow hot oil to be circulated and cooled outside of the motor through a high efficiency cooler. An absolute must for forced induction or track use.

Greater performance and 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. This will require the drilling of mounting holes to install this kit. Instructions are included. Stainless steel oil lines are built to our specifications by Goodridge, the leader in motorsports for high performance braided lines, and used in most of our Oil Cooler Kit applications.
