NGK - Spark Plug - #710

The NGK BP8HN10SP (#710) is a proven standard spark plug designed for dependable ignition, clean starts, and consistent performance across many automotive, motorcycle, and marine engine applications. NGK standard plugs are selected by more manufacturers than any other thanks to their reliable firing characteristics, durable construction, and long service life.

This plug features a solid copper core to promote efficient heat transfer and steady combustion performance. A triple gasket sealing process helps eliminate gas leakage past the shell for a more secure seal and consistent operation.

For durability in demanding environments, the BP8HN10SP uses a 99% highly pure alumina silicate insulator for strong dielectric protection and heat resistance. Corrugated ribs help prevent flashover, while cold rolled threads are designed to reduce the risk of damage to the cylinder head during installation and service. The shell is finished with trivalent plating using silver chromate and zinc to improve corrosion resistance.
