Champion Spark Plugs have all of the qualities that have made Champion an industry leader. The plugs have a triple-coated shell for outstanding corrosion resistance and the industry's strongest triple seal assembly. Precision-rolled threads meet all manufacturer's requirements, and a copper core improves performance and plug life.

SPARK PLUGS RV8C (4/PK) (121) are responsible for supplying the spark that ignites the air/fuel mixture, resulting in an explosion that causes your engine to produce power. These little but effective plugs create an arc of electricity between two leads that are not touching yet close enough to allow power to pass through.

SPARK PLUGS RV8C (4/PK) (121) is an electrode that has a copper core, which improves conductivity and heat regulation for better overall wear. These maritime spark plugs are made to withstand high engine loads without overheating.

Key Features:
