Lumang invention na pala ito... Someone just approached me today on this, claiming 20 - 40% improvement on fuel economy on my 15 year old car. Same concept, injecting hydrogen into you air intake. The kit's about 10k++. Have there been any recent advancements in this area to make this more feasible & practical to use in your everyday car? I'm interested but if the claims aren't true, I'd rather spend my money somewhere else.
