Copper spark plugs

Copper spark plugs have a copper core central electrode and a nickel alloy ground electrode. They are relatively inexpensive and widely available, but may have a shorter lifespan compared to more advanced spark plug designs. They are also suitable for use in standard engines and operating conditions.
