# NGK G-Power Spark Plug Box of 4 (TR5-1GP)

NGK G-Power Platinum spark plugs are the best single platinum spark plugs at an economical price. G-Power plugs feature a fine wire platinum center electrode and a trapezoidal cut ground electrode that offers increased durability, improved fuel efficiency, lower emissions, faster starts and quicker acceleration over conventional nickel spark plugs. An excellent upgrade for vehicles which used nickel alloy spark plugs originally. For better performance consider upgrading to a NGK Iridium IX plug. For even greater performance consider upgrading to a NGK RUTHENIUM HX plug.

-   RECOMMENDED USAGE: Lower cost alternative to double precious metal spark plugs or as an upgrade to OE nickel alloy spark plugs
-   Pure alumina silicate ceramic insulator provides superior strength and better heat transfer
-   Trivalent metal plating for superior anti-corrosion and anti-seizing properties
-   Trapezoid cut ground electrode reduces quenching
-   Corrugated ribs prevent flashover
-   Copper core aids in heat removal
-   Triple seals prevent leakage
