NGK BLYB Spark Plug Box of 6 (BM6F)

The NGK BLYB spark plug features a solid 98% pure copper core, which is key for dissipating heat effectively and ensuring good conductivity. This helps maintain optimal operating temperatures across a wide range of conditions, contributing to reliable performance. These plugs are built with a high-grade alumina silicate ceramic insulator, offering superior strength and better heat transfer compared to standard ceramic materials. This design helps prevent flashover, keeping the spark focused where it needs to be.

NGK applies trivalent metal plating to the exterior of these spark plugs. This treatment is notable for its superior anti-corrosion and anti-seizing properties, making installation and later removal much easier. The triple gasket sealing is another important detail, effectively preventing combustion gas leakage to maintain consistent cylinder pressure. These plugs are designed for longer life and consistent performance, making them a solid choice for many small engines.
