NGK (4548) CR9EK Standard Spark Plug, Pack of 1
NGK standard spark plug is manufactured to enhance the performance of any vehicle. It is constructed from durable materials that are corrosion and abrasion resistant. The spark plug insulators are made of 99 percent pure alumina silicate, allowing for longer insulator noses for reduced fouling. Solid copper core for greater spark, superior heat dissipation and conductivity. Longer insulator nose prevents fouling. Corrugated ribs on insulator prevents flashover. Dual ground electrodes for more consistent spark. Triple gasket seal eliminates combustion gas leakage and the zinc dipped shell prevents corrosion.
