Tornado Fuel saver

[39mto39g]

I just watched a commercial on the Tornado fuel saver, This thing fits into the air tube of your engine and they clamed more gas milage and more HP. They even had the car on a dyno to show more hp. They said it made a better air/fuel mixture. $75. for this peace of tin.
Now I have no I dea what most of you's car inteligence is, so hears some advise.
1. There is no air fuel mixture outside the cylinder on most cars today (Fuel injected). The fuel is put directly into the cylinder and is atomized.
2. as soon as the air passes through the Tornado it straightens out, or it wouldn't continue on its way.
3. and hears the most important one, Ford and GM could have 10-15 more hp and better gas milage just by putting this peice of tin in the air tube, OK, why don't they?
