Product Details

The NGK 91187 Iridium IX spark plug delivers superior ignition performance and extended service life for a wide range of automotive applications. Featuring a ultra-fine 0.6mm iridium center electrode, this plug provides improved throttle response, better fuel efficiency, and more complete combustion compared to conventional platinum or copper plugs.

Key Features:

  • Iridium center electrode for maximum durability and longevity
  • Tapered ground electrode reduces quenching for improved ignitability
  • Trivalent metal plating provides superior anti-corrosion and anti-seizing properties
  • Corrugated ribs on insulator prevent flashover
  • Pure alumina silicate ceramic insulator for superior heat dissipation
  • Copper core aids in heat removal from firing tip
  • Triple gasket seal eliminates combustion gas leakage

NGK Iridium IX spark plugs are engineered to meet or exceed OE specifications and provide reliable performance in demanding conditions. The iridium construction allows for a smaller center electrode diameter, which requires less voltage to fire while providing a more concentrated spark for better combustion efficiency. Ideal for both stock and modified engines seeking improved performance and reliability.
