No thermostatic plate, however if I recall there might be a bypass. Also during the last oil change a ball bearing and a spring fell out, not sure if it was the plate or the back flow preventer in the filter as I mangled the filter pretty good trying to get it off.
Line size is only an issue if the line in the most restrictive point, if the cooler was the most restrictive point then increasing line size would be useless. The core was designed for up to -12 so I think -8 might be a little small.
