Engineered for extreme competition and high-stress environments, NGK Racing spark plugs are built to withstand the rigorous heat and vibration of the track. The R7448A-10 features specialized electrode configurations designed for maximum durability and consistent ignitability where standard plugs might fail under pressure.

These plugs utilize a copper core for superior heat dissipation and a pure alumina silicate ceramic insulator for high thermal conductivity and structural strength. The trivalent metal plating provides a protective barrier against seizing and corrosion in the cylinder head, ensuring reliable installation and removal during service intervals.

  • Part Number: R7448A-10
  • Quantity: Box of 4 plugs
  • Trivalent Metal Plating: Superior anti-corrosion and anti-seizing properties.
  • Copper Core: High-grade copper core aids in rapid heat removal from the combustion chamber.
  • Pure Alumina Silicate Ceramic: Provides superior insulator strength and heat transfer.
  • Triple Seals: Prevents combustion gas leakage for consistent cylinder pressure.
  • Corrugated Ribs: Designed to prevent flashover and electrical interference.
