NGK WR5IX 7510 Spark Plug Iridium IX

Lowest price we found
£28.82
The NGK R6601-10 is a conventional spark plug from the NGK Standard range, with a 14 mm diameter and nickel-alloy construction.
Its copper-cored centre electrode carries heat away from the firing tip quickly. The plug can run cooler under load while burning off deposits at low speed, helping it resist 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.
