Champion spark plugs manufactured products with high-quality materials to achieve standard specifications consistently. Champion engineers ensure that the spark plugs are created to match specific combustion chamber circumstances. Champion spark plugs offer a diverse range of spark plugs to ensure that the optimal spark plug for each engine type and application is always available. SPARK PLUGS (880) has a copper core electrode for enhanced conductivity and heat regulation for long-term use. It works by receiving high voltage electricity at one end and producing a spark at the other. That spark ignites the engine's air-fuel mixture, resulting in the combustion that starts your engine. It is a vital device to your boat engine's performance and durability. It is one of the good indicators of imminent engine problems. Key Features: It is resistant to fouling. Superior corrosion resistance. Reliable and guaranteed efficiency. Improved conductivity and heat control for improved overall durability.
