If it looks too good to be true, it probably is...

They don't work, as most reasonably intelligent people would suspect.  A car magazine over here tested a very simmilar product, and measured only power loss.  With the amount of swirl/tumble given to the mixture as it goes through the inlet of port of a cylinder, stiring the air a little bit at the air intake is simply not going to do anything (a fart in a hurricane springs to mind).  If it did, you'd expect with the millions of $'s of research they spend, that car manufacturers would have adopted this years ago.  If something that could literaly be made for a few cents could even give a fraction of the claimed benefits, they would be fitting them.

It's quite incredible just how many snake oil products exist in the automotive sector.  Do people become more guilible after buying a car?
