It funny how the last 2 threads that have mentioned itb's have ended up in a knowledge war.
It's not intended as a knowledge war because it's not a who's know more, i merely wanted someone to explain clearly the logic behind using ITB's and keeping aircon being pointless. I felt it to differ from reality. At the end of the day it boils down to an imperceptible degradation in performance to maintain aircon but allows you to maintain what is to some a valued feature of the car.
