NGK standard spark plugs with copper cored centre electrodes for wide heat range. Copper's superior heat conductivity dissipates the heat of combustion away from the firing end, preventing hot spots that can lead to pre-ignition. Copper cored electrodes also mean that longer insulator noses can be used to protect against fouling.
