Has any one tried these?
 

I was watching tv a couple nights ago and i saw this add for something called the tornado or some shit like that! It's supposed tocreate even air flow and add power and gives better gas miliage? I personally think it's all a crock of shit! Has any body actually tried it?:eek:

They are a bunch of crap. Sport Compact Car tested on on a 1st Gen and it added 1hp.
