Have you ever come across pre and post vent temperature data (intake, coolant oil, engine compartment)?

Its allowed so everyone does it but I've never seen any actual data on it (but that doesn't mean that it doesn't exist). Same for the front inner fender liner vents.
Maybe someone else will jump in who has some data to share...
