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
Oil Cooler Kit is complete and includes all the necessary adapters,
fittings, and hoses you will need for installation. This will

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
