This NGK LTR6A-10 90338 is a conventional nickel-alloy spark plug with a copper-cored centre electrode, part of the NGK Standard range.
The copper core carries heat away from the firing tip quickly, allowing the plug to run cooler under load while burning off deposits at low speed. It resists overheating and fouling better than a plain nickel plug.
It is a direct replacement where a conventional plug is specified. The plug is easy to inspect and re-gap, and has triple-seal construction against gas leakage and a corrugated insulator to prevent flashover.
