Product Details

The NGK 7554 (ZNAR7AIX) Iridium IX spark plug is built for performance enthusiasts. It has a fine wire iridium center electrode that gives a consistently stable spark.

  • Iridium's very high melting point suits modern high-efficiency engines
  • Tapered cut nickel ground electrode improves starting, idling and throttle response
  • Copper core helps remove heat and conduct current
  • Pure alumina silicate ceramic insulator for strength and heat transfer
  • Trivalent metal plating resists corrosion and seizing, so the plug installs and removes easily
  • Corrugated insulator ribs help prevent flashover
