Air Razor, does it work ?

These units you install in your air stream boast about improved horse power and fuel savings. they write > Q> Wouldn't putting the Air Razor in the air stream just create a restriction?
No, almost all of the time, intake tubes are larger and can flow much more volume than a vehicles MAF sensor (if equipped), Airbox, Intake Fittings or Throttle body. And since our item installs in the intake tube, it will never become a restrictive factor. In fact the vortex created will increase air speed and density therefore allowing the truly restrictive areas (such as the MAF sensor, Airbox or Throttle Body) to flow more volume of air.
Has anyone tried these?

It's a gimmick. I personally haven't tried it but have read on other forums where others have.... Don't waste your money.
