NGK SPARK PLUG - DPR8EA-9

NGK DPR8EA-9 Spark Plug – 4929 NGK Standard spark plugs are engineered for long life and optimum performance. The DPR8EA-9 features a trivalent metal plating that provides superior anti-corrosion and anti-seizing properties, ensuring the plug remains easy to remove even after thousands of miles of heat cycles. With a corrugated rib design to prevent flashover and a pure alumina silicate ceramic insulator, this plug delivers a consistent spark in the harshest off-road conditions. Features: Copper Core Technology: Deeply inserted copper core aids in heat dissipation, preventing the plug from overheating while maintaining excellent electrical conductivity. Trivalent Metal Plating: The silver-colored finish eliminates the need for anti-seize and protects the threads from the moisture and debris common in dual-sport riding. Cold-Rolled Threads: Precision threads prevent cross-threading and damage to cylinder heads during installation. Corrugated Ribs: Prevents electrical "leakage" or sparking between the terminal and the shell (flashover), ensuring the energy reaches the combustion chamber. Zinc-Chromate Coating: Provides a durable barrier against rust and corrosion.
