Iridium, like platinum, is a precious metal and has extraordinarily superior properties for a spark plug electrode, for example high-temperature withstand, high strength, and low resistance. In order to further improve oxidation resistance at high temperatures, DENSO developed a unique new iridium alloy containing rhodium.

Spark plug with single side electrode An electric spark on the spark plug. A spark plug (sometimes, in British English, a sparking plug, [1] and, colloquially, a plug) is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within ...
A spark plug's ability to transfer heat to the car's cooling system is based on the length of the insulator nose and the materials used for the center electrode and the insulator. Standard spark plugs in modern engines have a copper center electrode core surrounded by a nickel alloy, which you can see at the tip of the plug.

- Spark plugs usually need to be changed every 30,000 miles.
- Spark plugs alone (without labor) cost around just $10. Higher-end options can cost as much as $25.
- You can expect to pay for the cost of the spark plug and about $100 to $200 in labor costs. The total typically averages between $200 and $300.
A spark plug is made of a center electrode, an insulator, a metal casing or shell, and a side electrode (also called a ground electrode). The center electrode is a thick metal wire that lies lengthwise within the plug and conducts electricity from the ignition cable hooked to one end of the plug to the electrode gap at the other end.
Tip is made of copper, nickel, chromium or other precious metals. The metal carries the high voltage through the spark plug so it can spark when it goes across the small gap between the central electrode and the side electrode. 5. Ground or Side Electrode. Located on the side of the metal, it extends into the combustion chamber to create the ...
Feb 2, 2021 · When new, multiple-side electrode spark plugs perform the same as single, “J” electrode spark plugs. In other words, using multiple side electrodes is a way for the plug manufacturer to save money on precious metals while maintaining proper spark operation over the plug’s life.

How do spark plugs work?
The ground electrode can come in a variety of shapes and sizes. Some (multi-ground spark plugs) can even feature two, three and four ground electrodes. These, however, do not create more sparks than a spark plug with one ground electrode. For both single and multi-ground electrode spark plugs, only one spark is created at a time.
