Our wildcat hydrogen boost kits will improve your gas mileage NOW....... What you experience is a more efficient burn, cleaner engine, more power and higher mileage per tank. Wildcat hydrogen booster systems work in virtually any conventional motor vehicle or internal combustion engine that burns gasoline or diesel fuel.
Our hydrogen boosters have been proven effective on CAT, John Deere, Case, Ford, Kubota, Massey Ferguson, New Holland, McCormick, and Caterpillar tractors. Hydrogen produced by the Wildcat 3000 and the Wildcat 9000 hydrogen boosters will change the complexion of any fuel. The "Burn Rate" of air-fuel mixture will make an engine utilize every ounce of diesel or gasoline. Smoother engine operation is noticeable due to lower RPM speeds. The Wildcat 3000 and Wildcat 9000 hydrogen boosters work in harmony with any type of fuel delivery system by injecting hydrogen into the air intake of the engine.
