NGK Racing spark plugs (MPN R6725-115) are engineered for high-stress competition environments where extreme heat and vibration are constant factors. Designed to withstand grueling racing conditions, these plugs utilize specialized center electrode configurations to maximize ignitability and ensure consistent performance under high-load scenarios.

  • Trivalent Metal Plating: Provides superior anti-corrosion and anti-seizing properties, ensuring easier installation and removal even in high-heat cycles.
  • Pure Alumina Silicate Ceramic Insulator: Delivers exceptional dielectric strength and efficient heat transfer.
  • Copper Core: Aids in rapid heat dissipation to help prevent pre-ignition and potential engine damage.
  • Triple Seals: Robust construction that prevents combustion gas leakage for consistent cylinder pressure.
  • Corrugated Ribs: Engineered to prevent electrical flashover between the terminal and the shell.
  • Specialized Insulator Nose: Optimized configuration improves throttle response and helps prevent fouling in racing applications.

This package contains a box of four (4) NGK Racing R6725-115 spark plugs.
