Product Description
Ride with confidence using the POWERMADD SPARK PLUG E3 31 from Knobtown Cycle.
Key Features
- 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
