Don’t try this in California. Smog rules are very strict—You cannot modify your engine in any way, even if it improves mileage or reduces smog. Guys have switched their systems to propane and passed the smog check with all the indicators reading zero, only to be told they had to rip it out again. Rules are rules you know.

No smog issues are involved. Zero, nada, zilch. The system runs on water. That little device extracts HHO gas instantly from a quart of water. You only have to add more water about once a week. HHO or Browns Gas burns like Hydrogen. Cleanly except for a small amount of water vapor. The whole system costs about $ 400.

The Aussie have taken over the patent. People are running on Browns gas for free. Water is free. Free is a very good price and a lot better than paying $ 3 per gallon for gasoline.
