At idle, very true. Air speed thru the tube would be slow enough that the hot tube would transfer some heat to the air. On the interstate with the motor running 3,000 RPM (or at least thats what mine usually runs ) then the air speed thru the tube would be high enough that the tube "should" transfer very little heat to the passing air.
On a similar note, all of Weber guys who are running open element filters just above the carb are pretty much in the same boat as you. The only difference is ours is not directly above the exhaust, but is still subject to the same radiator blast of air. If I remembe correcty Mikey got an adapter for his weber and moved the cone filter in front of the radiator... wonder if he can tell the difference in seat of the pants power? Or is 1-2 HP just not that noticable on our trucks LOL
