Hey does anyone have this thing it looks like a food shredder, and is sopost to increase hp. Here is a link to a company that sells them.
www.spiralmax.com
I have also seen them on TV I believe they were cheaper on tv. By looking at it I think it might fit in my airbox (E420).
If anyone has it did it do anything and are you happy with it (I don't think anyone has it though).
Oh yea anyone rember what the one on TV was called.
Thanks
Subman

the one on tv was called the tornado. looks like b.s. to me, I can think of no way in which the spiraling of wind into a fuel injected car would help. It might be useful on a carbuerated engine, to cut down on turbulence through the venturi tubes, but it's doubtful.
