But when I went out with the splitter, I was stunned how much of a difference it made. Neither coolant or oil temps never went past 215F even with full 20 min session going full send. It was cooler around 55F ambient temp but during same temps last year coolant would still get up there to 240F so it definitely made a difference. I assume the splitter helps directing a lot more air into the radiator.
I installed the GTM supercharger kit 1.5 myself back in 2013 and it was tuned right after by RT tuning. It served me well for all of this time and hard 33k miles.
