Higher charge density alone won't improve efficiency, though it will boost power. Most of the favorable effect of moisture in the intake has to do with "wet compression," in which the moisture absorbs some of the heat of adiabatic compression, thus reducing temperature rise and reducing the work expended in compression, which translates into a net horsepower gain. The effect is stronger if a phase change - vaporization - takes place, so I would expect a fogger (which puts fine liquid droplets into the air to be vaporized) to be VERY effective in a dry climate due to precooling before compression, remaining effective to some degree in wetter climates like the Philippines, where I live.
