Hydrox Systems HHO Kit uses the extra power of your vehicle alternator and break the bonds between the molecules of the water. They produce gas from the water – Oxy-Hydrogen also called HHO gas. HHO gas is the most potent and calorific fuel in nature. The produced HHO gas goes to the air-fuel mixture of any Internal Combustion Engine, making combustion of fossil fuels such as Petrol, Diesel, LPG, or CNG more complete and efficient. As a result, you get fewer emissions and reduced fuel consumption
