So I'm sure everyone has heard of that little metal "tornado" thing ur supposed to put in ur air intake pipe just before the manifold...and this is supposed to increase HP, gas mileage, and so on....my question is, has anyone actually seen results from this little addition on a dyno? I'm curious cuz i'm still seeing advertising for it and the freakin thing costs like $70!

 

haha that thing is such a pos. the only thing it does is get in the way of air

 

No kidding, those are a scam and a half.

 

ya that's what i figured
