Not disagreeing with you on the debate but the guys post just stated his research and asked if anyone had a stock one there wasnt a question on what he should do or which is better just a statement.
I agree on the ram air going to the intake vs the engine bay by far. Owning several "big rigs" I know the fuel savings and performance of cold air going in the engine vs the engine bay on a large level. I took 4 Identical trucks engine and body wise and simply wrapped all the hot parts in fiberglass and all the charge pipes with a insulated foil type wrap and cooled the tempature at the intake manifold 19 degrees pulling a 7% grade with 80,000 lbs and gained 6lbs of boost seeing my turbos are not regulated by a waste gate. over a 6 month period one truck averaged .13MPG gain and the other gained .20 over all with multiple drivers. That right there was saving me $30,000 plus a year just on two trucks.
So the first thing I saw on my new viper powered beautiful engine was a heat soaking hp robbing aluminum intake manifold, granted there isnt much you could do with that short of dumping ice on it every 5miles my point is cooler air has more density and more oxygen per cm2 so the computer can add more fuel per glorious stoke!
