NGK SPARK PLUGS Spark Plug - B8S 3810

If you're running an engine under sustained high RPM or variable load conditions, spark plug thermal range becomes critical—too cold and you'll foul, too hot and you'll detonate. The NGK B8S 3810 delivers the thermal stability needed for aggressive driving without sacrificing plug longevity or ignition reliability. Whether you're tuning a street machine or logging hours on track, these plugs maintain consistent performance across a wide operating window.

Built with high alumina ceramics and a deep-seated copper core, the B8S 3810 handles temperature swings that would compromise lesser plugs. The nickel alloy tip resists erosion, keeping your ignition timing precise mile after mile.
