Will see. I will track it probably in October (depending how kids daycare goes all things considered) and see temperature. I coded my mpg gauge to show temp. so we will see if I have any issues.There is a kit out there I believe that has everything included from BMW for the 52s. I think it was more of an issue for the turbos, one of our customers tracks her 328xi and said she never saw above 2 ticks past the halfway, so I think the change would be negligible. Not worth the investment most likely.
