Anybody ever see one of these?

I saw one of these for the first time yesterday when we installed one in a Peterbilt semi at work. The driver swore by it, claiming a 40% increase in fuel mileage. Any one else ever see one?

well judging by the concept and chemistry involved, they sure have a good sales pitch, it seems like it would work, but depending on how they go about making it for specific cars makes it sketchy. :roll:

I guess they sell a basic design and leave it to the buyer to adapt it to their vehicle. The idea makes sense in theory, but at $230+ it's a pretty expensive experiment
