ACDelco Conventional Spark Plugs are precisely engineered and manufactured to provide everyday reliability and efficient performance.
Available for most older vehicle makes and models, ACDelco Conventional Spark Plugs feature:
- A copper-core center electrode that helps provide improved heat transfer to the tip, giving you the reliability youre 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.
