NGK WR5IX 7510 Spark Plug Iridium IX
£10
£25.04
The NGK R6601-9 is a conventional nickel-alloy spark plug with a copper-cored centre electrode.
The copper core carries heat away from the firing tip. The plug is designed to run cooler under load while burning off deposits at low speed, and the construction resists overheating and fouling. It has a triple seal against gas leakage and a corrugated insulator to prevent flashover.
It is described as a direct replacement where a conventional plug is specified, and as a choice for classic engines, motorcycles, garden machinery and everyday servicing. It is easy to inspect and re-gap.
