Auto lite Copper Core Spark Plugs deliver quick starts, smooth acceleration, and improved fuel economy.
The copper-glass seal bonded insulator, terminal post, and center electrode ensure a tight seal that is 100 percent leak-proof, while the full copper core electrode optimizes plug life and improves heat transfer.
High alumina ceramic is featured in Copper Core Spark Plugs for high dielectric strength, and a steel shell ensures installation robustness.
The multi-rib insulator reduces the danger of 'flash over' to prevent misfires, and the copper core center electrode provides higher thermal conductivity.
Engineered with a high nickel alloy center and ground electrode, these spark plugs offer extended life.
Auto lite has sold over 11 billion plugs and has over 100 years of engineering experience.
The Auto lite brand has provided the automotive aftermarket and Original Equipment manufacturers with the highest quality ignition products since its inception.
