E3 38 spark plug | POWERMADD

Product description

Unique electrode shape maximizes the power created by the spark plug Diamond Fire technology Electrode is a combination of performance and 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 cylinder power stroke The result is more complete combustion and an improvement in engine performance
