HHO Generator 2.0
head over to your local hardware store and purchase them. Then once you have all the parts that are needed to build your own hydrogen booster you can begin to try and construct the hho booster. However I personally recommend picking up a HHO Booster guide before doing so. The guide will run you in the range of $40-100. While you should be able to pick up all the parts for under $100. Saving you at least that much every single month on gas.
