Interesting... I have a Cruze Eco with a 1.4T engine that takes FOREVER to warm up when it's cold, and it gets cold here in Ottawa. I wonder what kind of gains this could provide in warm up times?
I'm planning a full block heater install, so that should do it for the most part, but are the potential mileage gains worth the effort beyond that?
What is the theory behind the WAI increasing mileage? Is it simply that an engine pulls more manifold vacuum for a given torque output at lower intake air temperatures? My car is turbocharged, so I'm not sure if a WAI would do anything... any heat gained at the intake might just get lost through the intercooler.
