im not sure on temp differences since im waiting on my PTS 9X11 converter to show up. but just be the looks of the radiator and the looks of the inside of it i can tell you it will run cooler thats for sure. also it is alot lighter. the only reason i got mine is because my buddy bought the old radiator out of my car for 250 so the new pts radiator only cost me 250 out of pocket and i couldnt pass that deal up.
