Yes it's a scam, and yes it does work.
A vortex is not the fastest way through a passage, in fact it's pretty
slow. Just watch how long a soap bubble takes to get down the spinning
water in the drain. Or if a store around you still has that yellow
vortex thingie you drop a penny into to watch it twirl endlessly before
going down the hole, you can compare that to droping the penny straight
down the side. So clearly this is not the fastest way through the
intake manifold.
But, if an engine has a mixing problem, a device like this can help.
Enter lawnmower engines. They have lousy carburetors (big drops of
liquid gasoline), relatively long manifolds and slow rpms. Hence they
tend to suffer from fuel drop out, particularly at idle and such. So
the factories tend to install a tornado like corkscrew in their intake
manifolds to stir things up and keep the gasoline from dropping out and
stalling the engine.
Moral of the story? If your friend drives a lawnmower, the tornado
might work. If he drives an automobile, it won't.

A guy at work is asking me about buying a Tornado air twister for the
intake
of his Dodge Shadow. He watched the infomercial and they claim that it
twists the air in the intake so it can go into the engine faster, thus
improving gas mileage and giving you more power. It looks like a fan,
and
has no power to it. The fan turns by the air moving over it.
