It uses NGK's Standard Spark Plug construction: a solid copper core center electrode for strong heat dissipation and conductivity, a nickel center electrode tip, and a nickel ground electrode, all housed in a ceramic insulator body. The shell is treated with corrosion-resistant plating so the plug threads in and backs out cleanly during routine maintenance. A 5000-ohm resistor design is built in to help suppress ignition noise. This plug is a factory-equivalent replacement for the Yamaha OEM spark plug LFR-6A110-00-00, and is designed to fit 2001-2006 Mercury outboard engines and 2000-2005 Yamaha outboard engines. The M10 x 1.0 thread size matches these outboard applications. As with any spark plug, always check your engine's maintenance manual and only install the plug type and heat range recommended by the engine's original equipment manufacturer; 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 NGK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 3672\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNGK Part Number:\u003c\/strong\u003e LFR6A-11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 087295136720\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance:\u003c\/strong\u003e 5000 ohms\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\u003eThread Size:\u003c\/strong\u003e M10 x 1.0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulator Material:\u003c\/strong\u003e Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 9.9 x 2.0 x 2.8 centimeters (H x L x W)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e2001-2006 Mercury outboard\u003c\/li\u003e\n\u003cli\u003e2000-2005 Yamaha outboard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eYamaha OEM LFR-6A110-00-00\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat outboard engines does the NGK LFR6A-11 spark plug fit?\u003c\/strong\u003e The NGK LFR6A-11 (stock number 3672) fits 2001-2006 Mercury outboard engines and 2000-2005 Yamaha outboard engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this the same as the Yamaha OEM spark plug?\u003c\/strong\u003e Yes, the NGK LFR6A-11 replaces the Yamaha OEM spark plug LFR-6A110-00-00 and is built to the same specification.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the thread size on the NGK 3672 spark plug?\u003c\/strong\u003e M10 x 1.0 is the thread size for the NGK LFR6A-11 spark plug.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat electrode materials are used?\u003c\/strong\u003e Copper forms the center electrode core with a nickel electrode tip, and the ground electrode core is also nickel, on this NGK LFR6A-11 spark plug.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much resistance does this spark plug have?\u003c\/strong\u003e 5000 ohms of resistance is built into the NGK LFR6A-11 (stock 3672) to help reduce ignition interference.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the NGK 3672 spark plug weigh?\u003c\/strong\u003e The NGK LFR6A-11 spark plug weighs 0.15 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine NGK part or an aftermarket copy?\u003c\/strong\u003e It is a genuine NGK Standard spark plug, manufactured by NGK under stock number 3672 and part number LFR6A-11, not a third-party copy.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order this spark plug?\u003c\/strong\u003e One NGK LFR6A-11 spark plug (stock 3672) is included per unit ordered.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between this and NGK's iridium or platinum plugs?\u003c\/strong\u003e The NGK LFR6A-11 is a standard nickel-electrode plug, while NGK's iridium and platinum lines use different center electrode tip materials;
