Vehicle Fitment Information
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. The flame front moves toward the piston faster, moves heat into the combustion chamber faster and creates a more localized pressure. The result is more complete combustion and an improvement in engine performance. Sold each.
