I thought the nismo T-stat was a waste of money before I bought it. It does run cooler than stock by about 25*, but the most important part is the larger diameter of the valve. It is about 20-30% bigger than stock which I instantly noticed an improvment in temp stability and over cooling performance. It flows a lot more coolant. And you will notice it is you track your car. Also an oil cooler makes a big difference on coolant temps.
