Failtastic stuff there,take air thats flowing,then spin/restrict it so that is has to straighten out and flow again?
dumbest thing ever to advertise for a diesel.

 

These have been proven to work on carbureted gassers. Once again, this WONT work on a force inducted engine.

 

How does it work on a carb, the air has to go straight through the venturi's, and this would actually decrease your CFM because its a restriction. If it was to be in each intake runner, then I could see it doing something...but not before them. The air is going to straighten out in the manifold, and in the head where it turns down into the valve opening... Its about as useless as a poopy flavored ly pop.

 

Its purpose is to increase velocity and air density. This is why the modern intake systems are designed the way they are. You dont want a direct shot to the intake or carb. A flow path with at least one radius is needed to speed up the air which in turn increases density. We all know that engines like cool dense air. These have been proven to increase mileage and are being used in military vehicles and the transportation industry. Like stated before, it would be useless on a force inducted engine.
