The WAI was a snap took 5 minutes wish I would have done this earlier. 3" dryer hose fit perfectly on the airbox ran the tube between block and exhaust manifold. My manifold has a heat sheild which I hope will keep the cool air from getting in.
Had a few stops to make so took it for a spin the temps were steady between 114 and 125 and the ignition timing seemed normal. I'll have to see what the temps do at highway speeds.
The WAI hose does stay warm after shutdown but I don't have enought time on it to have a good feel for it yet. Yes, the foil cover the heated fuel line that runs on top of the radiator hose to help hold the heat in.
I tried the hose thing with the warm air. I saw a solid 1mpg increase on the freeway but the problem was it lowered my power. As long as you're always driving on level roads this mod will be okay. But if you ride up hills like I do most of the time the engine will downshift the tranny which in result will require more fuel.
But the foil on the fuel lines is clever, it will bump up the fuel temps and make for better atomization which will increase fuel economy.
I've got a lot of rolling terrain so I'll see how it does. Our temps are alot higher down here also which should help with the IAT. I think I remember Compaq888 that you were have shifting problem until you reset the TCU, was it doing the downshifting before and after the reset?
