absolutely. if the air going into the tb is as hot as the bay then the power will be down\/ \/ \/ with a good intake duct- big, straight etc then the air entering the turbo will be nice and cool and the cooler air will keep the duct cool. the turbo will heat the air of course, but the cooler the air/ shorter the distance it has to travel from the filter to the turbo is the less it will heat. then it will depend on the size/ flow of the 'hot side', the intercooler and 'cold side' piping. the larger/ shorter/ straighter that all is will result in cooler air temps at the tb. that's why piping choice and intercooler size is so vital when chasing power...
