NGK WR5IX 7510 Spark Plug Iridium IX
£10
£17.43
The NGK DFH6B-11A / 6858 is a conventional nickel-alloy spark plug with a copper-cored centre electrode, part of the NGK Standard range.
Its copper core carries heat away from the firing tip quickly, allowing the plug to run cooler under load while still burning off deposits at low speed. It is a direct replacement where a conventional plug is specified, including marine and powersports types fitted to outboards and personal watercraft. The plug has triple-seal construction against gas leakage and is easy to inspect and re-gap.
