Has anyone ever used the Tornado air management system?
They claim to increase airflow into the engine, thereby giving the car better mileage and increased horsepower. The cost of one of these units is $69.98 plus tax and shipping.
The company says the Tornado will increase your gas mileage by an average of 1 - 2 MPG.
They say it is also easy to install along with no further maintenance required.
My sister had one of these installed on their Nissan Frontier 4 by 4. She says that she did see a noticeable improvement in mileage. She did not notice an increase in HP output.
This sounds good to me. I'll have to test one of these units out and see if it works.
We'll have to let you know on a future post.
