Hi,
I found this item which is licensed by the EPA conducted tests on vortex generators that produced results as high as 20 horsepower and 24% increases in mileage.
1- The Turbonator
Turbo
and spiralmax
Spiral .
Any idea about it, because where i live i pay 4$ per Gallon (4 Liters). So. I'm searching if i can find a solution to increase the mileage.
Cheers
Elie
