Air Vortex System
I'm seeing things about Air Vortex Generators. It looks like a piece of machined aluminum that's meant to be installed behind the air filter. It has fins that apparantly force the air to spiral in the intake system. IThere are no electrical hookups. Just install in the air intake system.
These companies claim that this adds up to 20 - 30% improvements in gas mileage, and better horsepower.
I'm kind of skepticle about this. Anyone put on of these things in? Or know more about it?
Any responces would be appreciated.
