The NGK LMAR8A-9 4313 is a conventional nickel-alloy spark plug in the NGK Standard range, with a copper-cored centre electrode.
The copper core carries heat away from the firing tip quickly. The plug is described as running cooler under load while still burning off deposits at low speed, helping it resist overheating and fouling compared with a plain nickel plug. It is a direct replacement where a conventional plug is specified. The construction includes a triple seal against gas leakage and a corrugated insulator to prevent flashover; the plug is easy to inspect and re-gap.
