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.
STILLEN offers 2 options for oil cooler cores:
STILLEN Setrab Series Oil Cooler
Swedish-made Setrab oil cooler cores are renown by top racing teams around the world for their excellent cooling abilities, as well as use on OEM vehicles such as Aston-Martin, Ferrari, Jaguar, Audi RS, AMG Mercedes, Lamborghini, etc. Setrab have been used in virtually all of STILLEN coolers for years with excellent results.
STILLEN Gold Series Oil Cooler
We've had an oil cooler core built to our exacting specifications, and is a very economical choice compared to the brand name Setrab core kits. We've tested the units side by side, and performance of oil cooling is identical. Gold series cores also have integrated fittings, which eliminates the possibility of cross threading the fitting to the cooler core. All other hardware, Goodridge stainless lines, thermostatic plate, etc. remains the same.
In the case of the Nissan Titan, STILLEN also offers a large filter and adaptor kit for some vehicles that adds 2 1/2 quarts of oil capacity. It is an option that works in conjunction with the STILLEN oil cooler kit. It cannot be used without the oil cooler. Kit includes adapter and oil filter. These filters are readily available at any auto store from all filter manufacturers.
NOTES / EXCLUSIONS: Oil Cooler Kit cannot be mounted on a 350Z with a long and low aftermarket cold air intake system due to interference issues. These kits will not fit Nismo 370Z models without custom modifications (instructions not provided for Nismo models).
**IMPORTANT!: All Oil Cooler Kits that have Thermostatic Plates MUST use Fram Oil Filter #PH3950 or equivalent to insure proper seal!
