Use On Demand Hydrogen (HHO Gas), to increase the efficiency of your engine resulting in better mileage and lower emissions. The kits install easily, and use only distilled water and an electrolyte activator (included in kit). There are no modifications to your engine, and if you remove the kit, or turn it off, the settings revert to original. All kits include the compact generator, a reservoir, a

nd special one micron dryer filter to insure only pure hydrogen reaches your engine. Hydrogen and oxygen are injected into the air intake of your engine, where it is drawn in and mixed with your cars intake air, and fuel. The hydrogen causes the gas or diesel to burn faster and cleaner, which is why emissions are drastically reduced (50-75% on some vehicles!)
After kit is setup, you only need to top off the tank with water from time to time. www.hhokitsdirect.com
