E3 RESISTOR SPARK PLUGS FOR HARLEY-DAVIDSON

E3 RESISTOR SPARK PLUGS FOR HARLEY-DAVIDSON 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

A truly premium performance plug
