lol everytime i go to ebay and search for 92-94 maxima stuff i always see like 20 of these tornado gas savers, wierd thing is, is that when bid is almost up, people pay up to $20 or more for these things. Ive never heard of anyone who got one, was wondering what the hell its about and if it actually works? Im pretty sure there wouldn't be a difference, and not sure if i want some fan thing sittin inside my intake. but with gas prices these days, im trying to get most gas mileage possible.

It's a crock of sh*t. It's a chunck of sheet metal bent in all sorts of directions. The idea is to create a "vortex" in the airflow for better fuel mixture. Unfortunately, fuel is injected just upstream of the intake valves, so there's no time to "mix". A chunk of metal, regardless of its shape, is going to restrict airflow. Even if it was able to create a slight spin in the intake airstream, that would collapse within milliseconds due to the numerous turns and changes in pipe diameter incoming air has to endure to reach the cylinders.
The theory itself is bull. Fuel needs to be atomized into vapor as much as possible to burn. If you inject atomized fuel into a spinning airstream, the centrifugal force alone would sling all the fuel vapor toward the outside of the airstream and make it condense back into a non-burning liquid. Don't buy it.

A fool and his money will part quickly.Do not buy this thing! The shortest route between two places is a strait line,NOT A SPINNING TORNADO!!
