Identified by NGK as model B8HS-10, it uses a solid copper core center electrode for efficient heat dissipation and consistent conductivity, paired with a nickel center electrode tip and a nickel standard ground electrode for durable, long-lasting operation. The plug carries a resistance rating of 1 Ohm and a 14 millimeter thread, and it is treated with corrosion-resistant plating that makes installation and removal straightforward.\u003c\/p\u003e\u003cp\u003eThis spark plug is engineered as a direct interchange for engines originally fitted with Johnson\/Evinrude part number 0503705 or Yamaha part number B8H-S1000-00-00, making it a straightforward replacement option when servicing compatible outboard engines. Each unit ships individually and is ready to install as a routine maintenance or replacement part. As with any spark plug swap, confirm the correct heat range and thread specification against your engine's original equipment manufacturer maintenance manual before installing, since using an incorrect 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 5126\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel Number:\u003c\/strong\u003e B8HS-10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance:\u003c\/strong\u003e 1 Ohm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround Electrode Tip Design:\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\u003eThread Size:\u003c\/strong\u003e 14 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 3.89 inches L x 0.94 inches W x 0.66 inches H\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 087295151266\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eJohnson\/Evinrude 0503705\u003c\/li\u003e\n\u003cli\u003eYamaha B8H-S1000-00-00\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the NGK 5126 spark plug?\u003c\/strong\u003e The NGK 5126 is a standard nickel spark plug, also identified by NGK as model B8HS-10, featuring a copper core center electrode and a nickel ground and center electrode tip.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the NGK 5126 cross-reference to a Johnson or Evinrude part number?\u003c\/strong\u003e Yes, the NGK 5126 (B8HS-10) is interchangeable with Johnson\/Evinrude part number 0503705.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs there a Yamaha equivalent to the NGK 5126 spark plug?\u003c\/strong\u003e Yes, the NGK 5126 (B8HS-10) is interchangeable with Yamaha part number B8H-S1000-00-00.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat thread size does the NGK B8HS-10 spark plug use?\u003c\/strong\u003e The NGK B8HS-10, sold as part number 5126, has a 14 millimeter thread size.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the electrical resistance rating of this spark plug?\u003c\/strong\u003e The NGK 5126 spark plug has a resistance rating of 1 Ohm.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat materials are used in the NGK 5126 spark plug's electrodes?\u003c\/strong\u003e The center electrode core is copper for efficient heat dissipation, while the center electrode tip and the standard ground electrode are nickel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the NGK 5126 spark plug weigh?\u003c\/strong\u003e The NGK 5126 spark plug weighs 0.15 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the package dimensions of the NGK 5126 spark plug?\u003c\/strong\u003e The NGK 5126 ships in packaging measuring 3.89 inches long by 0.94 inches wide by 0.66 inches high.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the NGK 5126 an OE-style or aftermarket-only spark plug?\u003c\/strong\u003e The NGK 5126 (B8HS-10) is a standard NGK plug built to OE-style specifications, corrosion-resistant plated for reliable installation and removal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many spark plugs come in one NGK 5126 package?\u003c\/strong\u003e The NGK 5126 spark plug is packaged and sold as a single unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat ground electrode configuration does the NGK 5126 use?\u003c\/strong\u003e The NGK 5126 (B8HS-10) uses a standard ground electrode configuration with a nickel core material.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if the NGK 5126 is the right replacement plug for my engine?\u003c\/strong\u003e Confirm the correct heat range and thread specification against your engine's original equipment manufacturer maintenance manual before installing the NGK 5126, since the wrong plug can reduce performance or damage the engine.\u003c\/p\u003e","brand":"NGK Spark Plugs","offers":[{"title":"Default Title","offer_id":49028253024475,"sku":"NGK-B8HS-10","price":3.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/B8HS-10__78166.1737887362.500.750.jpg?v=1785165218","url":"https:\/\/www.goodvibesmarina.com\/products\/ngk-spark-plug-5126-b8hs-10-copper-core-nickel-electrode-14mm-thread","provider":"Good Vibes Marina","version":"1.0","type":"link"}
