It uses a solid copper core center electrode with a nickel tip, giving it superior heat dissipation, strong conductivity, and a broad heat range for consistent combustion. The ground electrode uses a standard configuration in nickel, and the whole plug is treated with corrosion-resistant plating so it threads in and comes back out easily, even after seasons of exposure to a marine or outdoor environment. Electrically, it is rated at 1 Ohm resistance.\u003c\/p\u003e\u003cp\u003eThe NGK B8S (3810) is fitted to a specific range of outboard engines and small equipment: Evinrude outboards (1951-1973), Johnson outboards (1957-1973), Sears outboards, and Wizard outboards (1966-1971), as well as Craftsman (Sears) and Pioneer chainsaws, Pioneer generators, and International farm engines. Always check your engine or equipment's original maintenance manual to confirm this is the correct plug before installing, since the wrong plug can reduce performance, hurt 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 3810\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNGK Catalog Part Number:\u003c\/strong\u003e B8S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance:\u003c\/strong\u003e 1 Ohm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround Electrode 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 14 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 087295138106\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOutboard - Evinrude, 1951-1973\u003c\/li\u003e\n\u003cli\u003eOutboard - Johnson, 1957-1973\u003c\/li\u003e\n\u003cli\u003eOutboard - Sears\u003c\/li\u003e\n\u003cli\u003eOutboard - Wizard, 1966-1971\u003c\/li\u003e\n\u003cli\u003eChainsaw - Craftsman (Sears)\u003c\/li\u003e\n\u003cli\u003eChainsaw - Pioneer\u003c\/li\u003e\n\u003cli\u003eGenerator - Pioneer\u003c\/li\u003e\n\u003cli\u003eFarm engine - International\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the NGK B8S spark plug (stock number 3810) fit?\u003c\/strong\u003e The NGK B8S spark plug, stock number 3810, fits outboard engines including Evinrude (1951-1973), Johnson (1957-1973), Sears, and Wizard (1966-1971), plus Craftsman (Sears) and Pioneer chainsaws, Pioneer generators, and International farm engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the electrical resistance of this spark plug?\u003c\/strong\u003e 1 Ohm - the NGK B8S (3810) is a standard, low-resistance design rated at 1 Ohm.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the center electrode made from?\u003c\/strong\u003e Copper.
