So just some fyi for people like me who got a 370 and had oil problems. It took a total of 2 months for Nissan to get me my oil cooler and installed, and oil change, FOR FREE. Had to go through Nissan North America. I had oil temps in the high 240's sittin in traffic. Cruising to work at 2 p.m. at 75-80 oil was at 225-235 with an ambient temp of 90's. I ran my car over lake hemet into palm springs. Hemet was 102 that day and started at base of hill with a 235, within a minute of running I hit 250. Backed out of it and it took forever for the car to cool. Went down into palm springs where it was 113. Turned right back around and gripped and rippped it. Withing a minute temp shot from 230 to 258. So I knew the car's problem was excavating heat. After dealing with Nissan Consumer Affairs on this they installed the cooler today and I test drove it. Honestly can say that I ran 90% on my car on mountain driving and the cooler held up really well. Temp outside was 93 so it was slightly cooler than the june weather I experienced, but still good to test in. The car never got above 225. After the mountain peaked and was on somewhat level driving grounds, it only took about 2 minutes of 60ish in 6th gear to cool the car down to about 185. It stayed there. Coming back from palm springs was fun because it is more quicker wide open throttle type of driving mid to high 3rd gear most of the way. Again 225 and that was it. Temp was 105 during the run. All of my cooler run was done with the a/c on because I wanted to see how it would do with the engine pullin the air conditioning and a full tank of gas. The bridgestones handled really well.
