An automobile air filter comprising a filter element, an outer hood receiving the filter element, and a plurality of metal electrodes arranged in the filter element. Each pair of the metal electrodes is connected by a cable and pass through the outer hood. A high voltage generator circuit is installed at appropriate location of an automobile for generating instantaneous high voltage to provide instantaneous high voltage power to each pair of metal electrodes, so that the metal electrodes generate high voltage flashes and ozone to purify the air flowing in the filter element and increase oxygen content in the air intake in the engine.
