It's BS.

They're ALL BS. All of them. The Vornado, magnets, browns gas, "modules", all of them.

In all likelyhood your 'module' is a resisitor you place in line with the intake air temp sensor to trick the engine into thinking the charge air is colder, thereby enriching the mixture. This is what they usually are - a $0.02 resistor.

The MOST effective device out there that can improve your gas milage is your right foot. Simply changing your driving habits can increase your milage by as much as 10%.
