Aggressive driving of the 370Z on a race track at sustained high engine speeds can cause increases in oil temperature and may activate this engine protection system. To avoid activation of this engine protection system and these reduced peak engine speeds, Nissan recommends an oil cooler be fitted to the 370Z before driving it on a race track. A Nissan Motorsports accessory oil cooler kit is available for customer purchase through authorized Nissan dealerships for race track use. The part number is 21300-SS370.

An oil cooler is not necessary for normal operation of the vehicle on public roads. The addition of an oil cooler would have raised the price of the car and potentially moved it out of the reach of some customers. Value has been a core principle of the Z car since the original 240Z and we choose to uphold this core principle by not adding additional costs that are unnecessary for normal use. For those individuals who choose to drive their vehicle on a race track, the oil cooler is available as an aftersales item.

The oil cooler is a Nissan Motorsports item and as such is sold without warranty, express or implied, unless expressly prohibited by law in which case the warranty provided is the minimum required by law. The installation of the Nissan Motorsports oil cooler does not, by itself, “void” the vehicle warranty. However any damage caused by the installation or use of this part is expressly excluded under the terms of the Nissan New Vehicle Limited warranty.

But on a normal driven car now that its broke in I dont have a prob with the oil temp and Im fairly heavy footed. I really think it calms down on the temp side after its broke in. Love the power.
