NGK 7164 TR55IX Iridium IX Spark Plug

  • NGK 7164 TR55IX Iridium IX Spark Plug NGK-TR55IX TR55IX

    Superior NGK Iridium IX Spark Plug is the next evolution in spark plug technology and performance. With a higher melting point and higher resilience to oxidation than platinum, iridium offers a dramatic increase in durability and service life.

    • Unique two-stepped centre electrode with a secondary micro-discharge burns off carbon deposits as they form.
    • Taper cut ground electrode ensures an excellent flame spread and improved vibration resistance.
    • A super fine centre electrode—just 0.6mm—for increased power, acceleration, fuel efficiency and ignitabillity.

    Using the NKG Iridium IX will Improve:

    • acceleration 
    • fuel consumption 
    • idling smoother
    • servicing life
