Abstract: An apparatus for the production of ozone for an internal combustion engine comprising a non-conductive shell having a first and second opening which allows air to flow therethrough and first and second electrodes disposed inside the shell. The first electrode is spaced a distance from the second electrode, the first electrode having a smaller diameter than, and being aligned axially within the second electrode. The first electrode permits air to flow therethrough. A high voltage source is connected to the first and second electrode, the high voltage source capable of producing a voltage differential on the first and second electrodes sufficient to cause the production of ozone. A change from oxygen to ozone occurs in the air flowing through the apparatus. The shell is preferably cylindrical.
