Champion pioneered the use of iridium in aviation and industrial spark plugs in the early 1970s. Now iridium, which has a stabilizing effect on ignition voltage and excellent wear characteristics, is quickly becoming the technology of choice for engine manufacturers worldwide.

Champion iridium spark plugs offer maximum performance regardless of engine or ignition type. Each plug has an extremely fine-wire iridium center electrode that is “laser-locked” to the center electrode, and a platinum V-trimmed ground electrode to ensure the longest life and greatest erosion resistance. Champion iridium plugs come with our exclusive Heat-Active™ alloy to reach operating temperatures quickly and maintain stable operating temperatures under varying engine loads.

Champion iridium plugs deliver a consistently focused spark that provides the greatest engine performance regardless of engine type or ignition system. Depend on this high level of performance throughout the life of every Champion iridium spark plug.
