My friend sent me some link for this "vortex generator" product a few days back. I thought nothing of it, just a scam or whatever I figured.
Was browsing EBAY and saw another thing on it though.. what the hell are these things, just curious??

This is something that came out a while back on TV. Is suposed to increase your gas milege and give u a couple of horses. Ofcourse they exagerate all the numbers to sell you the stuff. I personally don't any body that uses. Neither I see how can it give you HP if all you are doing is inserting another obstuction on the intake. I don't recomended. My prsonal opinion: Watch out on ebay of the stuff you buy. Many times they r scams. A friend of mine bought hwat was suposed to be a Mac CAI on ebay really cheap. Well the thing wasn't mac it was some Cr@@@@p that broke, went into his engine and messed it up. Message? Watch out what you buy on ebay.
