Spark Plug Regular Acdelco 41629

With coverage for most older vehicles on the road today and robust design,
ACDelco Regular Spark Plugs are an economical choice for solid performance.

ACDelco Regular Spark Plugs have a copper-core center electrode that helps provide improved heat transfer from the tip, giving you the reliability you’re looking for while providing better performance in most operating conditions*

• They are precisely engineered and manufactured to provide everyday reliability and efficient performance
• The copper-core center electrode allows for a longer insulator tip length for a given heat range, which helps prevent low-speed carbon fouling.
• 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
