All this over something so simple. His info says he lives in AL. LIke me here in NC we never see below 0 temps so his truck doesn't need this. I remove them in most of my vehicles. Doesn't matter what temp the intake manifold is, if it goes in cooler it'll be cooler at the head. Will it be the same temp at the head as the t-body? No but it'll be cooler than going through a hot t-body. What Mitsubishi told me is they put these in all vehicles for different reason than stated in the post. It was put there to prevent throttle plates from freezing in place in colder climates which could lead to accidents like Toyota had recently where customers couldn't stop the vehicle with the engine wide open. Nissan and even Chrysler have stopped using heated t-bodys recently since computer management and advanced sensors in the throttle body can tell if it's frozen or stuck and will put the vehicle into limp mode.
