Crap! Fell for this one not to long ago and put it on my Friebird. It actually restricted air flow!!! I would not recommend.

Still have in laying around somewhere if you want it...

I laughed at that

Save your money and do it right.

If you want fuel mileage than hypermill. Performance than stroke it.

TRASH! They are more of a restriction then anything. We tested them at the shop I worked at and they actually took more hp then they claimed to give.

open up the intake, better flowing exhaust. After that is a stroker..

Tornadoes and all of the similar products are something that I like to call 'snake oil.'

As in the old snake oil salesmen who used to sell quack medicine from horse drawn wagons.

Waste of money.

if you want to ram swirley air into your intake then just get a real turbo, yes its expensive but at least itll work how you want it to. if you see something like that that is cheap just think hmm if this was that cheap and worked than maybe it would be a popular item...
