Description
The NGK 3381 LZTR5AGP G-Power Platinum Spark Plug is an economical upgrade over standard nickel plugs, designed to deliver improved performance, durability, and efficiency. Featuring a fine-wire platinum center electrode and trapezoidal ground electrode, this plug enhances ignitability for faster starts, smoother acceleration, and better fuel economy.
Ideal for vehicles originally equipped with conventional nickel spark plugs, the G-Power series provides longer service life and reduced emissions without the cost of double platinum or iridium plugs. A copper core ensures excellent heat dissipation, while NGK’s trivalent plating protects against corrosion and seizing.
