Electrode is a combination of performance and new technology that results in an improved flame kernel shape. This flame front ignites the bulk air/fuel mixture faster, moves heat into the combustion chamber faster and creates a more localized pressure front for faster pressure rise during the cylinderpower stroke. The result is more complete combustion and an improvement in engine performance. A truly premium performance plug. Sold each. Thread 14mm.
