Have any of you guys seen this device ?? Promises more horses ?? From a bit of shaped pipe ??
Can't see it working myself...

If it was that easy to increase engine performance wouldnt all the car makers be creating a vortex on the intake?
I'd rather spend that money on a decent service, and I think it would have better results.
This, but it also works for magnets around your fuel lines and of course snake oil and electric turbos! Poppycock I tells ye!I'd rather spend that money on a decent service, and I think it would have better results.
It says "It creates a swirling cyclone of air within the combustion chamber,"
Sounds far fetched to me. It might well create a swirling column of air in the intake plumbing which might speed up air flow (might also slow it down?) to the AFM/plenum but as for creating a faster flow into the combustion chamber, that would be down to the design of the plenum and the inlet manifold wouldn't it? I see it's an American advert which probably puts it beyond the scope of the The Sale of Goods Act. caveat emptor.

Bear in mind that the engine isn't getting air blown in (apart from Pete's!) but the air is going through under vacuum, so any vortices are going to be "straightened out" to a laminar flow pretty quickly. If vortices are good, why have so many people spent so much time porting and flow-testing cylinder heads and inlet manifolds to get the air flow as laminar as possible?
In any case, how can a vortex in the air intake survive passing over a flat throttle butterfly, into a large plenum chamber (bearing in mind that the purpose of a "plenum" is to equalise pressure (or vaccum) for more even distribution), then change direction down individual intakes, past the injectors and into the cylinders?
I can see how it might assist fuel atomisation in a carburettor venturi, but in a multipoint fuel injection system? No chance.

Ahhh I hate these things! 
Turbulent flow is good for getting around sharp(ish) corners but is very draggy. Laminar flow is very low drag but is very fragile.
Ideally you would want laminar flow all the way through you induction system until the inlet valve(s) which induce a nice swirl in the flow as it enters a cylinder so the direct injection fuel can mix fully with the air. That would give the smallest losses with the most power. That is pretty much impossible though as any slight disruption to the flow, or even travelling in a pipe for too long will cause it to trip to turbulence.
You do not at any point want to introduce turbulent flow or restrict the flow in the inlet. It will increase the resistance of the induction system and reduce the amount of air getting to the cylinders and therefore the power. This thing will definitely reduce power not increase it.
This article tests various 'fuel savers'. The worst vortex generator decreased power by 10% and increased fuel consumption by 20%!
