Iridium Power Technology

Fifty million years ago, an asteroid composed almost entirely of the precious metal Iridium (Ir-77) struck the earth creating the Gulf of Mexico. From this catastrophe came a metal with properties ideal for spark plug construction. Using this element, DENSO has evolved spark plug design to a new level.
