The OEM stat is rated to start to open at 186F; you can prove it for your self, just take an OEM stat and suspend it in a beaker of water with a thermometer in it, apply heat, and watch what temp it starts to opens at (186F), and what temp it is fully open at, which is much higher.............
The 215F+ running temps are real, try hooking a scanner with PID capability up to the car and take it for a ride, you just might be surprised at how hot it gets....... Then repeat the same test on a car with the 160F stat and see what you get; the "proof is in the pudding"..........
