Do I need one?
Id run heated if at all possible. You can tell with an AF meter where you are heated and not. If you heat, you can really lean out your carb as the fuel is not sticking to the cold intake. Air cooled VW guys add heat to their long intakes, makes tuning a lot easier. The 1-2 HP you lose if you run a heated intake (debateable) wont be noticed but it will run more consistantly. Id run a hybrid dutra and modded heater side if it were me and I had the option.
