About the product

The NGK CMR4A 5474 is a conventional nickel-alloy spark plug with a copper-cored centre electrode and a 10 mm diameter.

Its 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, helping it resist overheating and fouling compared with a plain nickel plug.

  • Part of the NGK Standard range
  • Direct replacement where a conventional plug is specified
  • Triple-seal construction against gas leakage
  • Corrugated insulator to prevent flashover
  • Easy to inspect and re-gap
