Hi,

I see auctions on eBay and other website about this Velocity Turner that you simply install between the air filter box and the throttle body and instantly you have better gas mileage and HP.

You can read more information from the eBay auction at the Item number: 330099217719. It states that it works for BMW X5s.

Has anyone heard of this before? Does it really work? Has anyone bought it and used it? It only cost 10 bucks. Thanks for any feedback......Jimmy
