Sorry, I also have no tested documented data.
However -
My WAI plus grill block plus 180 degree thermostat do a nice job keeping things warm. Even around 30-40 degrees, engine temp is around 190-195 F and intake is around 80-90 F. So I figure its like a spring or summer day as my engine and computer see it.
My WAI is several holes cut in the OEM air box below the filter, plus duct tape covering most of the oem intake snorkel port. The small open part reduces the intake moaning sound a good bit. The cuts pull warmed air from the radiator. Once warmrd up IAT is quite stable.
Stock HX thermostat is 172 deg and gives 182 temp because it reads water from the radiator. 180 deg tstat gives about 190-195 if u have a nicely managed grill block.
