NGK G-Power Spark Plug Box of 4 (TR4GP)

The fine wire platinum center electrode in these NGK G-Power spark plugs requires less voltage to fire, which means faster starts and improved acceleration. They feature a trapezoidal cut on the ground electrode, a design that helps reduce the quenching effect and offers increased durability compared to standard nickel alloy plugs. These are a solid option for vehicles originally equipped with nickel alloy plugs, providing a noticeable upgrade in performance and fuel economy without breaking the bank. They fit a wide range of vehicles, including models like the Chevrolet Impala, Buick Lucerne, and Pontiac G6.

NGK builds these G-Power plugs with a pure alumina silicate ceramic insulator for strength and better heat transfer, while the trivalent metal plating on the shell helps prevent corrosion and seizing, making them easier to remove later. The copper core inside aids in dissipating heat away from the plug tip, and triple seals are used to prevent any combustion leaks. This well-built design ensures reliable performance and longevity, making them a popular choice for many applications.
