Default Hot Air Intake?

Ok you are all going to think I'm crazy... I was reading on another forum about "hot air intakes." The theory being opposite of what we live by in the more power world. They claim to get an increase in MPG by having the engine injesting thin hot air, thus tricking the computer into delivering a less dense fuel mixture. Within the contraints provided in the PCM of course. Personally I cant see this being a good thing for an engine but I have been brainwashed by HP. I dont know, maybe on a small 4cyl this might be a good tool? I am happy with the MPG and power of my Bonne as it is so... No HAI for me.

It appears that a WAI (warm air intake) is more effective in winter driving, but has the opposite affect in summer driving - strictly on the MPG value.

From what I have read, the MPG increase is negligible and by fooling the PCM with the warmer air, you can actually lean the motor to the point where you can cause damage if you are not tuning accordingly.

There'* lots of claim to its increase in MPG, but I need to see more scientific data to truly believe it'* value.

Right thats what I was thinking. I know about cold start heat risers and egr usage to warm up an engine but these guys do some pretty odd things.. Some of the tricks they do for aero seem ok but some of the things they do for mileage makes me laugh

Don't sound like a good idea to me. Perhaps they can get one of those tornado air intakes.

Maybe they should grease the inside of the manifold so the air slips by better.. LOL

Ok.. No joke I saw a guy at the track once with a 2.3L Mustang.. Must be just about the slowest gas powered car made.. Anyway he had TWO of those blowers used on boats to vent fumes from the bilge hooked up to his intake. LOL I almost fell over.
