These Tornado gas saving devices are for carbureted and throttle body injected engines and increase miles per gallon and improve fuel economy.
The Tornado installs easily on your air cleaner or air inlet hose and its unique airflow dynamics create a swirling, fast-burn effect in the combustion chamber. This creates finer particles (atomized fuel) allowing better flame propagation and more complete combustion, resulting in gas mileage increases averaging 1 to 2 MPG. These figures are confirmed by road testing performed at an EPA-licensed emisssions lab.
To select the correct Tornado for your car or truck, remove the air housing cover lid and measure the height from the base of the housing to the lid at 3" away from the center. This is most easily accomplished by removing the air cover lid and placing a flat edge across the top of the air filter, then taking a height measurement from the base to the flat edge at 3" away from the center of the carburetor/throttle body.
Next, repeat the same measurement with the lid. Finally, add or subtract the lid height from the base height, depending upon whether the lid drops below the top of the filter or rises above the filter.
After measuring your air housing, use the measured height clearance to select the Tornado 'kc' unit that fits your application.
