Woo Woo Woo...
Just a big big word of warning, it clearly works so well if you fit too many to your vehicle the fuel saving will go into the pos ... or neg and the fuel tank will start to fill up!!
So if you are "making" fuel you will need to comply with some Gov fuel std and no doubt pay Gov tax.
You have been warned...
