It uses a copper core center electrode that improves conductivity and gives precise heat range control, so the plug wears evenly and delivers dependable, proven performance over time. The design resists fouling, a common problem in marine ignition systems exposed to rich fuel mixtures and inconsistent run times, and it carries superior corrosion resistance to stand up to the humid, saltwater-adjacent environment around a boat engine. The plug is engineered to resist overheating under sustained heavy engine loads, helping prevent pre-ignition and detonation that can damage pistons and valves over time. Built to ISO and SAE standards, the Champion L78V is manufactured to the same specifications automotive and marine engine builders rely on for consistent, repeatable ignition performance. It is sold as a single plug (1 count), making it easy to order the exact quantity needed for a full tune-up or a single-cylinder replacement. Buyers replacing worn, fouled, or corroded spark plugs on marine engines can use the Champion L78V as a direct equivalent to the Bombardier part numbers it replaces, without hunting down original equipment through other channels.\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 CCH833M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChampion Spark Plug Number:\u003c\/strong\u003e 833M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 14mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore Material:\u003c\/strong\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTop Material Type:\u003c\/strong\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 037551005147\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1 spark plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.15 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBombardier 507992\u003c\/li\u003e\n\u003cli\u003eBombardier 509922\u003c\/li\u003e\n\u003cli\u003eBombardier 389471\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the copper core electrode in the Champion L78V spark plug do?\u003c\/strong\u003e The copper core center electrode in the Champion L78V (CCH833M) spark plug increases conductivity and allows for precise control of the heat range, which improves overall wear and keeps the plug firing consistently under load.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Champion CCH833M a direct OEM replacement or an aftermarket copy?\u003c\/strong\u003e The Champion L78V (CCH833M) is manufactured by Champion, the original spark plug maker, and is built to ISO and SAE standards as a quality OEM-type replacement plug rather than a third-party aftermarket copy.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat thread size does the Champion L78V spark plug use?\u003c\/strong\u003e The Champion L78V spark plug, part number CCH833M, has a 14mm thread size.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich OEM part numbers does the Champion L78V spark plug replace?\u003c\/strong\u003e The Champion L78V (CCH833M) replaces Bombardier part numbers 507992, 509922, and 389471.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Champion CCH833M spark plug weigh?\u003c\/strong\u003e The Champion L78V spark plug, CCH833M, weighs 0.15 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Champion L78V spark plug made for marine engines?\u003c\/strong\u003e Yes, the Champion L78V (CCH833M) is a marine spark plug designed to resist overheating under heavy engine loads typical of marine applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many spark plugs are included when ordering CCH833M?\u003c\/strong\u003e Each order of the Champion L78V spark plug, CCH833M, includes 1 spark plug (unit count of 1).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Champion L78V spark plug resist fouling and corrosion?\u003c\/strong\u003e Yes, the Champion L78V (CCH833M) is designed to resist fouling and offers superior corrosion resistance, both important in the damp, salt-exposed conditions marine engines run in.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Champion L78V spark plug?\u003c\/strong\u003e The UPC for the Champion L78V spark plug, part number CCH833M, is 037551005147.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the Champion L78V spark plug handle heavy engine loads without overheating?\u003c\/strong\u003e Yes, the Champion L78V (CCH833M) is specifically designed to resist overheating under heavy engine loads while maintaining dependable performance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Champion L78V spark plug's electrode made from?\u003c\/strong\u003e The Champion L78V spark plug, CCH833M, uses a copper core electrode for its center electrode material.\u003c\/p\u003e","brand":"Champion Spark Plugs","offers":[{"title":"Default Title","offer_id":49027462496475,"sku":"CHA-L78V","price":8.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/L78V__24891.1722518760.500.750.jpg?v=1785163548","url":"https:\/\/www.goodvibesmarina.com\/products\/champion-l78v-marine-spark-plug-cch833m-copper-core-replaces-bombardier-507992-509922-389471","provider":"Good Vibes Marina","version":"1.0","type":"link"}
