I appreciate the replies. I know excess heat is not your friend so the question that comes to my mind is; How well is the 370Z engine engineered to handle the 210-220 temps during "normal" daily driving and do so over a long period of time? Look into your crystal ball.
I mainly drive Spring - Fall, temps range 65 - 95, interstate, mountain roads or small amount of stop and go traffic. I live in a small town area. If I installed the 25 row cooler what could I expect my oil temps to drop to? Same question for a 34 row? From what I've read the oil temp should not be lower than 180. Thanks again. Trying to learn.
