Spark Plug Electrode Tip. only the center electrode is platinum tipped (1.1mm dia) which increases fuel consumption, drivability, and durability; when the tip of the spark plug turns white, it indicates that the engine is running too hot and lean. A new iridium alloy tip with a diameter of 0.4 mm is laser welded to the tip of the center electrode to make the center. The spark plug tip has been burned. However, it doesn’t necessarily mean the spark plug is bad. blisters on the insulator tip, melted electrodes, or white deposits are signs of a burned spark plug that is running too hot. As oxygen meets with the spark plug, fuel impurities and iron oxide react to cause the white residue. a good spark plug should have a light brown or tan color on the tip of the electrode, indicating that it’s functioning optimally. Any other color or mixture of colors shows there’s something wrong. center electrode, ground electrode, and/ or ceramic insulator tip are coated with a black, oily substance.
