It uses a solid copper core that improves heat dissipation and electrical conductivity across a broad heat range, backed by decades of use as an original-equipment plug design. The plating on the plug is corrosion-resistant, which keeps threads turning smoothly during both installation and future removal, reducing the risk of cross-threading or a seized plug at your next service interval.\u003c\/p\u003e\u003cp\u003eThis plug uses a standard ground electrode configuration with a nickel ground electrode and a nickel center electrode tip over a copper core, and it carries a 5000 ohm resistor to help suppress ignition interference. Each plug has a 5\/8 inch (16mm) thread size and ships one plug per package. It is intended as a direct fit for the engines listed below; always confirm the plug specified in your engine's owner or maintenance manual before installing, since using an incorrect plug can reduce performance and fuel economy or damage the engine.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e NGK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 7023\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpark Plug Part Number:\u003c\/strong\u003e CR6HS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance:\u003c\/strong\u003e 5000 ohm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround Configuration:\u003c\/strong\u003e Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround Electrode Core Material:\u003c\/strong\u003e Nickel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Electrode Core Material:\u003c\/strong\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Electrode Tip Material:\u003c\/strong\u003e Nickel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulator Material:\u003c\/strong\u003e Ceramic (alumina silicate)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 5\/8 inch (16mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1 spark plug per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.15 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury outboard, model years 2002-1995\u003c\/li\u003e\n\u003cli\u003eMariner outboard, model years 2002-1995\u003c\/li\u003e\n\u003cli\u003eYamaha outboard, model years 2004-1985\u003c\/li\u003e\n\u003cli\u003eHonda motorcycle, model years 1987-1985\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003eNo additional OEM cross-reference numbers are listed for this plug.
