E3.68 E3 Premium Automotive Spark Plugs (6-PACK)
E3.68 plugs are designed to deliver more power, better fuel economy and reduced emissions. A patented platinum electrode ensures maximum spark energy and durability. The triple-gapped design creates a larger spark flame kernel for increased ignitability and improved performance. The stepped insulator reduces quenching and heat transfer, while the tapered nose prevents fouling. E3.68 plugs are heat-treated to resist corrosion and provide maximum life.
