FUEL SAVING DEVICE is a catalytic converter uses the elements in the air to fine tune the fuel & air mixture entering the intake manifold to the chemically correct (stoichiometric) ratio (14.7 parts air to 1 part gas). More it distributes this mixture uniformly to all the cylinders of the engine. and recycles the unburned carbons into usable gases thus giving a higher fuel yield. During burst of acceleration and deceleration FUEL SAVING DEVICE chemically adjusts & help supply exactly the right fuel and air mixture (lean or rich) at the right time so that the engine can run powerfully, economically and without the air pollutants that results from poorly mixed, distributed and burned fuel. OTHER BENEFITS: * Fuel savings (gas and diesel) * Longer engine life * Quick acceleration with added torque * Less maintenance cost * Benefits visible upon installation * One year replacement guarantee * Durable; steel stainless; effective life 5-10 years * Easily removable & washable filter tip * Transferable from one vehicle to another
