Here is the sales pitch...

"Studies have shown stationary vortex generators greatly increase an engines airflow and fuel atomization for more horsepower (up to 15%) and better fuel effeciency (up to 30% increase). The idea is simple, spiraling air moves with greater velocity and efficiency through a cars intake tract. More air=More power, its that simple. Additionally the spiraling air atomizes the fuel better allowing for more complete combustion. Your cars computer reads the changes and compensates by eliminating excess fuel delivery, resulting in better fuel effeciency. Also, beleive it or not, vehicles with Auto Trans will shift smoother than ever"

Ok....I did this simple little mod two weeks ago. Just for giggles.

Increase power....YES! Especially 1st to 2nd at about 3500 rpm.....

Increase fuel efficiency......Well I did not go from 16mpg to 21mpg...but I have noticed and tracked and increased range of 60miles per tank and an increase of 1.2-1.5 mpg.....nothing wrong with that at these prices....

BTW...gas futures halted trading twice today.....now @70+ per barrel.

aye carumba!!
