AC Delco Conventional Spark Plugs are precisely engineered and manufactured to provide everyday reliability and efficient performance.

Available for most older vehicles, AC Delco Conventional Spark Plugs feature:
  • A copper-core center electrode that helps provide improved heat transfer to the tip, giving you the reliability you're looking for while improving its resistance to low-speed carbon fouling
  • Hot-tip insulator heats fast and fires hot
  • The nickel-chrome alloy on the ground electrode and center electrode sheathing resists wear from spark erosion and the corrosive environment of the combustion chamber

  • Does ACDelco R42TS fit your vehicle?
