NGK Standard Spark Plug — BPR5ES-11
Product Details

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.
