Diesels don't have a throttle plate, so you don't have a pumping loss problem from the T-plate.
UGH, i was thinking about this today because I have a d15z1 (VX) engine in a 96 civic hatch and have problems holding 65mph in lean burn, so i'm having to give it more throttle to (i'm assuming make more power) to maintain that speed. So if I make a Warm air intake, that is going to give me even less power, and then I won't be able to maintain say 60mph?

I was thinking that it wouldn't be incredibly difficult to make a "Y" valve that cuts off the cold air intake or hot air intake for whatever situation you desire. like using a choke on an old car to get it up to temp, then closing the choke. i could get the warm up the engine faster benefits of the WAI and then if i was in a highway situation where I needed more power to maintain higher speeds, I would just close that and open up my CAI.
