🔧 Product Description

NGK Iridium Spark Plug – Part Number: IFR6D10

NGK iridium spark plugs feature an iridium alloy on the centre electrode, welded on with a laser – one of the world's hardest metals, with a melting point of 2450°C, giving very high resistance to spark erosion and, on average, double the service life of a standard nickel spark plug.

⚙️ Key Features

  • Longer service life
  • Trivalent metal plating provides superior anti-corrosion and anti-seizing properties
  • Corrugated ribs reduce the risk of flashover
  • Pure alumina silicate ceramic insulator, providing superior strength and better heat transfer
  • Triple seals prevent leakage
  • Copper core aids in heat removal
