surely this little thing you put in your intake box doesn't "Spool Up"
I mean, the only thing that COULD "spool it" would be in the incoming air, and obviously if the air itself is causing it to turn, well, it ain't going to have any energy of it's own to compress the air into the cylinders.
I believe the idea is simply to swirl the air, that will theoretically ensure a more complete mixture of the air and gas before it's injected into the cylinders.

Here's a thought to back my opinion...
It's like putting a fan in your window, gluing the blades to each side of the window, and saying it's cooler in the room.
The "vortex" that it creates does not last. The "twisting" air WILL NOT swirl all the way into your cylinders. Though the idea is based on water and it shows it works well, the effect is not the same inside a car. Water is far denser than air allowing it's momentum to carry much farther.
People go and get it, spend an hour installing it into their car, and since the whole device is biased on saving gasoline, people are going to be driving more efficiently; not slamming the gas off of every light, etc. I think the thing has a "placebo effect". If someone spends 80 bucks on this, of course they are going to say it works no matter what....People want their purchases to work out.

This thing is useless. The trick to good fuel economy is keeping your foot off the accelerator.
I'd like to see the tornado snake oil salesmen explain how the supposed 'tornado' of air created by this device gets around a huge restriction in the inlet path called the throttle plate. What are they gonna tell you, keep the throttle wide open so as not to interfere with the 'tornado'? What a load of crap.
The real beauty of this gadget is how it can lift money out of the pockets of the gullible.
