Spark Plug - R2525-10 - NGK

The NGK R2525-10 spark plug is engineered with features that support reliable performance in demanding conditions. Trivalent metal plating helps resist corrosion and seizing, while the pure alumina silicate ceramic insulator provides strength and supports heat transfer. Triple seals help prevent leakage, and corrugated ribs help reduce flashover. A copper core aids heat removal.
