NGK Standard Spark Plug — B8EG
Product Details

Pure race plug: solid-copper-core nickel construction tuned for high-RPM, high-cylinder-pressure engines where the heat range matters more than service life.

  • Compact, solid-copper-core design with a nickel ground electrode optimized for the heat range, not the service interval.
  • Heat ranges run colder than street plugs (typically NGK 8–10) so the tip stays out of the pre-ignition zone in built engines and forced-induction race motors.
  • Available in standard 14mm and racing 10mm thread sizes, in projected and non-projected tip geometries to match the chamber.
  • Solid terminal or removable nut variants — pick the one that matches your plug-cap style; check the variant title.
  • Short service life by design — these are race weekend plugs, not 30,000-mile street plugs.

Spec: B8EG
