It uses a copper core electrode that increases conductivity and improves heat control, giving the plug good overall wear characteristics even under sustained load. The plug is engineered to resist fouling and offers superior corrosion resistance, two of the most common failure points for spark plugs operating in a marine environment where moisture and salt exposure are constant concerns.\u003c\/p\u003e\u003cp\u003eChampion built the CCH931M (listed under Champion's own catalog as the QL82C, Champion Spark Plug # 931M) as an OE-type replacement, meaning it is designed to restore original engine performance rather than serve as a performance modification. It is intended to resist overheating under heavy engine loads, making it a dependable choice for boaters who run their engines hard. The plug carries UPC 037551005246 for easy identification and cross-checking against the original part being replaced.\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 CCH931M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChampion Catalog Model:\u003c\/strong\u003e QL82C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChampion Spark Plug Number:\u003c\/strong\u003e 931M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore Material:\u003c\/strong\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e RM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTop Material Type:\u003c\/strong\u003e Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1 spark plug (individually boxed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 037551005246\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eNo specific engine make, model, or year fitment is listed for the CCH931M; verify compatibility against your engine's original spark plug number before ordering.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBombardier 504082\u003c\/li\u003e\n\u003cli\u003eBombardier 503951\u003c\/li\u003e\n\u003cli\u003eBombardier 437684\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Champion CCH931M spark plug?\u003c\/strong\u003e It is a marine-grade OEM replacement spark plug from Champion, listed in Champion's own catalog as the QL82C and stamped with Champion Spark Plug # 931M.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the CCH931M cross-reference to any OEM numbers?\u003c\/strong\u003e Yes, the CCH931M is an equivalent replacement for Bombardier 504082, Bombardier 503951, and Bombardier 437684.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the electrode core made of?\u003c\/strong\u003e The CCH931M uses a copper core electrode, which increases conductivity and gives better heat control for good overall wear.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this spark plug resistant to corrosion?\u003c\/strong\u003e Yes, the CCH931M offers superior corrosion resistance, which matters for spark plugs used in marine engines exposed to moisture and salt air.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the CCH931M resist fouling?\u003c\/strong\u003e The plug is designed to resist fouling, helping maintain a dependable spark under normal marine operating conditions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the CCH931M weigh?\u003c\/strong\u003e The Champion CCH931M weighs 0.15 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many spark plugs are included?\u003c\/strong\u003e The CCH931M ships as one individually boxed spark plug per unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the CCH931M a genuine Champion part or an aftermarket copy?\u003c\/strong\u003e The CCH931M is a genuine Champion spark plug, sold under Champion's own QL82C catalog designation and marked with Champion's # 931M stamp.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the CCH931M perform like the original equipment plug it replaces?\u003c\/strong\u003e Yes, it is built as an OE-type replacement designed to restore original engine performance rather than change it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the CCH931M handle heavy engine loads without overheating?\u003c\/strong\u003e The CCH931M is designed to resist overheating under heavy engine loads, making it suited to sustained marine engine use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the thread size on the CCH931M?\u003c\/strong\u003e The CCH931M has an RM thread size.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Champion CCH931M?\u003c\/strong\u003e The UPC for the Champion CCH931M is 037551005246.\u003c\/p\u003e","brand":"Champion Spark Plugs","offers":[{"title":"Default Title","offer_id":49027462889691,"sku":"CHA-QL82C","price":4.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/QL82C__67422.1722483469.500.750.jpg?v=1785163558","url":"https:\/\/www.goodvibesmarina.com\/products\/champion-cch931m-copper-core-marine-spark-plug-ql82c-replaces-bombardier-504082","provider":"Good Vibes Marina","version":"1.0","type":"link"}
