I won't build an engine without one. I know what just 10 degrees of coolant temperature reduction can do for the engine. The factory knew too and the 987 and 997 illustrate it well.

I learned these things many years ago, but still today people want to argue with it, people always want to argue and the funny thing is most of them couldn't remove and replace their own thermostat if their life depended on it. If opinions were effective those people could move mountains.
