Engines nowadays; are designed and produced by producing more power with less fuel, at low emission values, noiseless and longer life if the engine is protected. Since the dust, soot, pollen, water particles etc. is found in the air, the engine needs a good air filtration. If a quality air filtration is not performed, the fuel consumption will increase by 30%. 1Gr powder per BG is enough for engine parts to wear out and fail. Engines need a high amount of dry and clean air in order to produce efficient power in long life.
