MR43T spark plugs come pre-gapped as specified by your engine manufacturer. Use only the spark plug listed in your engine owner’s manual. Using the wrong plug can reduce optimum performance, reduce fuel economy or cause damage to your engine. Spark plugs are easy to change with common spark plug sockets. The AC Delco ribbed suppressor seal extends resistance and prevents spark “flash over” and misfire. They 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. The AC Delco exclusive hot-tip insulator heats fast and fires hot to promote longer electrode life for miles of dependable performance.
- Made by AC Delco with nickel alloy tip, copper core and ribbed suppressor seal for durability and performance
- Check your engine owner’s manual for the correct spark plug and use only the plug as recommended by your engine’s original equipment manufacturer
- Nickel-chrome alloy sheathing on the ground and center electrodes help resist wear from spark erosion and the corrosive environment of the combustion chamber
- Replace all the engine plugs at the same time
- Don’t just clean used spark plugs, replace them with new plugs for better performance
