It uses a solid copper core center electrode for superior heat dissipation and conductivity, paired with a nickel center electrode tip and a nickel ground electrode in a Standard ground configuration. The broad heat range of NGK Standard plugs makes them an OE-cornerstone choice that has delivered reliable performance for decades. A 5000 ohm resistor is built into the plug to help suppress ignition interference. All exterior surfaces are treated with corrosion-resistant plating, which keeps threads turning freely so the plug installs and removes without seizing, even after extended service. The plug has an 18mm hex size for use with a standard spark plug socket. Because the correct plug depends on the exact engine it is installed in, always check your engine and maintenance manual and use only the spark plug your engine manufacturer recommends -- installing the wrong plug can reduce performance and fuel economy or cause engine damage.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
