My buddy has an LT 4 Vette and he e-mailed me about a product called the Spiralmax. It's one of those gizmos that creates a spiral effect on the incoming air. It proposes to give you more HP, torque and mileage. Anybody know if this or similar products really work?

 

The general consensus is that those things are crap so I wouldn't waste the money IMO

Ditto.

 

Those things are a waste of money(tornado/spiralmax) IMO

 

That's what I thought. If they were that good everybody would have one.
