Description:
The ACDelco R44LTS6 GM Original Equipment Conventional Spark Plug is engineered and validated by General Motors to meet strict OE standards for ignition performance and reliability. Designed as a direct replacement for factory-installed spark plugs, it provides dependable starting, smooth engine operation, and efficient combustion.
The copper core center electrode helps promote excellent heat transfer, supporting proper operating temperatures and improved durability. A nickel alloy center electrode tip and nickel ground electrode help maintain consistent ignition performance, while the built-in resistor helps reduce electrical interference with vehicle electronics.
ACDelco GM Original Equipment spark plugs are the same parts installed during vehicle production or validated by GM engineers, ensuring proper fit, function, and reliability for many GM vehicles and compatible applications.
