Making your Z run at 180-190 is like going back in time to the big muscle cars of the past. Do you know the modern engine has been running hotter and hotter as decades go by? Cars from the 70's use to run this cold. Reason why engines run hot now? well higher compressions, higher RPM limits, better fuel mixture, emission requirements, etc. There are definitely more benefits to running an engine hotter than colder. I've mentioned a few already. Like I said, there is no reason to obtain an oil cooler unless you track your car or live in an area that is too hot with many hills. I think some people just get an oil cooler for the sake of "modding" with no real reason for getting it only than to say they had one. of course there are many with legitimate reasons to have it
