E3 Resistor Spark Plugs

  • 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
