{"product_id":"champion-l86c-marine-spark-plug-copper-core-electrode","title":"Champion L86C Marine Spark Plug, Copper Core Electrode","description":"\u003cp\u003eThe Champion L86C is a marine-grade spark plug built as a quality OEM replacement for boat engines. It uses a copper core center electrode, which increases conductivity and improves heat control across the plug for good overall wear compared to standard designs. The copper core also helps the plug resist fouling, so ignition stays consistent even after extended runtime.\u003c\/p\u003e\u003cp\u003eMarine engines run hotter and under heavier, more sustained loads than typical automotive engines, and the L86C is designed to resist overheating under these conditions. Its shell is built for superior corrosion resistance, an important feature in the humid, salt-exposed environment marine engines operate in. Champion backs the L86C with dependable, proven performance, and the plug is also identified under Champion's own trade number 306, which appears on some packaging and cross-reference charts alongside the L86C part number.\u003c\/p\u003e\u003cp\u003eThis spark plug is a straightforward drop-in replacement for engines that call for the Champion L86C, delivering the same fit, thread size, and performance characteristics as the original equipment.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Champion\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e L86C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChampion Trade Number:\u003c\/strong\u003e 306\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 037551000340\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore Material:\u003c\/strong\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShell Material:\u003c\/strong\u003e Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 14mm x 1.25mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.15 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the manufacturer part number for this spark plug?\u003c\/strong\u003e The manufacturer part number is L86C, and Champion also identifies this same plug under its own trade number 306.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a copper spark plug?\u003c\/strong\u003e Yes, the Champion L86C uses a copper core center electrode, which increases conductivity and improves heat control for good overall wear.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat thread size does this spark plug use?\u003c\/strong\u003e 14mm x 1.25mm is the thread size for the Champion L86C marine spark plug.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Champion L86C resist corrosion?\u003c\/strong\u003e Superior corrosion resistance is built into the Champion L86C, making it suited to the humid, salt-exposed conditions marine engines run in.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this spark plug weigh?\u003c\/strong\u003e 0.15 pounds is the shipping weight of the Champion L86C spark plug.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is Champion trade number 306?\u003c\/strong\u003e Trade number 306 is Champion's own identification number for the L86C spark plug, used alongside the L86C part number on packaging and cross-reference charts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this plug resist fouling?\u003c\/strong\u003e Fouling resistance is part of the Champion L86C's design, helping keep the spark consistent through heavy marine engine use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the plug shell made from?\u003c\/strong\u003e An alloy steel shell houses the copper core center electrode in the Champion L86C spark plug.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Champion L86C an OEM-quality replacement?\u003c\/strong\u003e Champion manufactures the L86C as a quality OEM replacement plug rather than a generic aftermarket copy.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this spark plug handle heavy engine loads?\u003c\/strong\u003e Heavy engine loads are exactly what the Champion L86C is designed for, resisting the overheating that degrades performance under sustained marine use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat UPC is associated with this spark plug?\u003c\/strong\u003e UPC 037551000340 identifies the Champion L86C marine spark plug.\u003c\/p\u003e","brand":"Champion Spark Plugs","offers":[{"title":"Default Title","offer_id":49027462594779,"sku":"CHA-L86C","price":3.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/L86C__39971.1739459027.500.750.jpg?v=1785163548","url":"https:\/\/www.goodvibesmarina.com\/products\/champion-l86c-marine-spark-plug-copper-core-electrode","provider":"Good Vibes Marina","version":"1.0","type":"link"}
