Our local radio car guru, Leon Kaplan, keeps touting this product to improve mileage and power. He's normally very honest and doesn't recommend just anything unless he's convinced it works. I have a '00 GT and commute 60 miles a day and gas costs almost $2.50/gallon where I live so even 1-2 more mpg would be a big help. I've fallen for some scams in the past so I'm skeptical.

I used it in my 93 240SX and it did work giving me between one and two tenths in the quarter with my four banger. It did not work on my 96 Maxima although I found out much later that you need to disconnect the battery cable after installation of the Tornado unit for the computer to reset for the supposedly more efficient airflow. It is worth a try as their is a 30 day money back guarantee. All you are out is the freight. > >
