Extra heat shortens your engine's life and kills your components underneath the hood prematurely, particularly the wiring harnesses.

The 370Z is engine compartment, for some reason, is notorious for trapping heat. That is one of the major causes for high oil temp. One of my colleague has a 2013 EX37. Same exact engine set up, same exact radiator capacity and same exact fan temperature PCM codings ON/OFF durations as the factory 370Z.

Even on a real hot day for the EX37, on normal stop and go and occasionally hard drivings , the oil temp never went above 220F, where as my Z in the same condition can shoot over 240F easily. I am comparing both without oil coolers as they came originally.

So, TT the 370Z makes it very vital to keep the hood temp as low as you can. In addition to ceramic coating, I probably have to think about ventilating the hood somehow, or install a good carbon fiber one with nice ventilation built in.
