Funny how these posts are running concurrent with my individual situations. My 09 was flawless and my engine temps never ran passed 240 degrees once I. K&N filtered and synthed the car. This car now, which is an 11; with mild aggressive driving gets hot quick. Filters and synth has helped some but still gets hotter than my 09.
It seems the '12's are going to hit or miss as all Z's do regardless of the cooler. The 34 row NISMO cooler with thermostatic blocking plate seems like the only logical solution to this issue. Nissan I guess was looking for a cheaper solution and got cheaper results?
Break in could have an effect? But, at 55 degrees, temps seems a little extreme for the overall situation.
