Tornado Fuel Saver is a Scam!

Item:
Intake Fuel Saver/Power Adder

Alias:
Tornado Fuel Saver. Vortex Generator. Air Twister. Turbo Fan.

What it is:
An intake restriction.

What its supposed to do:
Create turbulence in the incoming airstream to allow for better fuel atomization. "Mixes the Fuel/Air like a tornado!!!!!!" This is "supposed" to theoretically allow the fuel to burn more completely in the combustion chamber.

What it actually does:
Creates a restriction in the intake stream, reducing the total power gain of the vehicle. Any turbulence or "vortex" caused by the devices is destroyed the second it reaches the throttle body plate. In some cases these devices can reduce power as much as 10%, while INCREASING fuel consumption.

These devices have been sold for years and are a complete and utter scam. Popular mechanics recently had an article on a variety of these devices and proved them all to be new age "snake oil".
