The NGK MAR9B-JDS is a conventional nickel-alloy spark plug with a copper-cored centre electrode.
The copper core carries heat away from the firing tip quickly. The plug is described as a direct replacement where a conventional plug is specified. Its construction includes a triple seal against gas leakage and a corrugated insulator to prevent flashover. It is easy to inspect and re-gap.
