NGK Standard Spark Plug — ZFR7F-11

Standard nickel-alloy spark plug from NGK — the same plug type the original manufacturer specifies for most factory-fit applications.

• Nickel-alloy center electrode with a copper core for stable heat range and reliable firing across the rev range.
• Trivalent-metal thread plating resists seizing and corrosion.
• Heat range and reach match the OEM plug — direct fitment, no jetting changes required.
• Gap is preset at the factory to NGK's reference; verify against the service manual before fitting.
• The economical baseline maintenance plug. Step up to Iridium IX or Laser Platinum if you want longer service intervals.
