No, I know all that -- I mean I thought they explicitly voided the warranty if you added the oil cooler. Not saying it's legal or fair, but if the OP is concerned about that, it would be good to know if there's a potential battle to be had or if Nissan just assumes the oil cooler doesn't affect the warranty.

In other words, if the warranty isn't an issue, he can get whatever oil cooler he wants -- he doesn't have to get the Nissan one.

Called the dealer, they said the Nissan and Stillen oil coolers would not void the warranty unless it was proven to cause a problem with the car. Installation of any another manufacturers/retailers product will void my warranty if they find out I have the part on the car.

Stillen's don't fit the NISMO without modification so, I'm left with the Nissan cooler which is supposedly back ordered.

Would love to get the 34 row Z1 installed on there, cheaper and just as big as the NISMO. But alas, I'm screwed with warranty issues.

thats the case with all oil coolers. will not void the warranty unless that part caused te issue. Its called the law. not a dealerships word. They cannot void a warranty on a car due to seeing a mod or change. They have to show that installation of the part, caused a problem , if/when a problem occurs. And thats it.

Thus, all oil coolers will have the ame affect on your warranty. So your options are really limited to which one you think is best. Also, you can research this and find it posted quite a few times. If your dealerships tells you differently, they dont know wtf they are talking about which is about the norm with most dealerships service dept's.

In fact, there are still employee's on this forum who could tell you the same.

And lastl, z1 oil cooler doesnt require any modification (except for flipping the harmonic balancer 180degres which really doesnt do anything). As for others with nismo, dont know.

not going to get into a pissing match with you.. Other oil coolers will work and are cheaper.. your nismo is not special.

I'm just wondering why Nissan will also offically stand behind the Stillen one... what's so special about that one relative to any other?

Stillen has a special relationship with Nissan. Back in the Z32 days, there was a Stillen 300zx that was sold in Nissan dealerships, and Steve Millen was their factory driver who won many titles in the USA for Nissan.


Regardless, why is everyone crapping on the OP? the more people who complain to Nissan, no matter how many times they say the car is ok, they may eventually cave in, or at least put the liquid cooler they have on the 350 on our car.

Whatever dude. If thats the case then you probably shouldn't be spouting off with one liners like these little sparkles of humility...

Or this?

Or this?

I heard what you had to say, we differ in opinion. You dealt with your oil cooler your way, I'm dealing with it my way. Never claimed my way is better than yours but, seems you think I am an idiot for trying my way and feel the need to tell me so. I'm not hurting anyone by trying to get Nissan off their *** and I'm not hurting anyone by being cautious about voiding my warranty. Whats your fuckin deal man?
