There is not hard external air to air oil cooler.

If you look at your oil filter housing, you'll see coolant lines feeding into it. Coolant cools the oil in the housing prior to the oil shooting into the motor. This is a pretty standard oil cooler. Standard meaning, its pretty standard on normal cars. I'm pretty surprised due to the fact that other "sport" cars like Evo's and STI's have rather large external air to air coolers.

Do the 2013 come with the same oil cooler? Haven't removed the cover on mine to check yet.

It has it.

I had a proper 25 Row GTM oil cooler installed on my 2012, it is actually cooling now. Along with the Uprev fan mod it is great, nothing over 195, and I've raped the car (how can I not after installing FI CBE haha).

So I think it is a real shame what type of oil cooler comes standard on 2012/2013 models... not sports car worthy.

Here's a photo of the factory oil cooling component on my 2012...i hesitate to call it an actual oil cooler though.

Possible to use OEM oil cooler on 09~11 model ?

IMO that whole design is very poor. But what do I know? I don't work at Nissan, I just consume their products. I knew it will have issues as soon as I found that Nissan was installing a "heat exchanger" not a oil cooler per say. And the construction of the oil adapter looks like can easly corrode/wear out thus creating and even bigger problem. "Hint Hint" water oil mixture. I'm just saying :eek:

I was wondering what this whole setup was when I changed my oil today. A water oil cooler, interesting...

Yeap, Nissan has been using them for years on the Maxima's. No issues with them failing at all. It works, it is just not going to cool the oil down any lower than coolant temp, it will actually be 10-20 deg higher.

The Maxima? Really? And it took them three years to figure out they needed one on their sports car? Nissan you crazy.
