NGK WR5IX 7510 Spark Plug Iridium IX
£10
£45.72
The NGK R2349-9 4418 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 designed to run cooler under load while burning off deposits at low speed, resisting overheating and fouling better than a plain nickel plug. It is a direct replacement where a conventional plug is specified and is used for classic engines, motorcycles, garden machinery and everyday servicing.
It is easy to inspect and re-gap, with triple-seal construction against gas leakage and a corrugated insulator to prevent flashover.
