Since I bought my gas guzzler Dodge with a 4.7 liter V8, I've searched for ways to save gas. I've experimented some myself by installing an Airaid throttle body spacer, a K&N drop in filter and fiddling with acetone-with some success.

I've been intrigued by those of you who have been experimenting with HHO. I unfortunately though, don't have the discipline that many of you have to experiment as you have. (Kudos to you for being pioneers).

I am looking for a somewhat off the shelf package that I can use on my Dodge (and install myself--I'm somewhat handy). I of course want a good bang for the buck, (a high producing device for the money). Does anyone have a suggestion? I am leery of buying something that might be snake oil (or near snake oil) so I'm asking you.
