Abstract
A method of manufacturing a spark plug, the method including the step of: securing an electrode tip to at least one of a side ground electrode or a center electrode of the spark plug, the electrode tip comprising a platinum-based alloy comprising 20 to 35% by weight of palladium, from greater than 0 to 15% by weight iridium, and the balance of the alloy being platinum, all % by weight being based on the total weight of the alloy.
