{"product_id":"champion-ql78c-marine-spark-plug-replaces-bombardier-502179","title":"Champion QL78C Marine Spark Plug, Replaces Bombardier 502179","description":"\u003cp\u003eThe Champion QL78C is a marine spark plug built as a quality OEM-type replacement for outboard and sterndrive engines. It features a copper core electrode that improves conductivity and heat control for good overall wear, helping the plug resist fouling and deliver dependable, proven performance across heavy engine loads. The copper-core design gives strong corrosion resistance, so the plug holds up in the wet, salt-exposed conditions typical of marine use. Champion also catalogs this plug under the designation Champion Spark Plug # 883, so buyers may see it listed either as QL78C or as plug number 883 -- both refer to the same part. It is offered as a direct OEM cross-reference for Bombardier engine applications using OEM part number 502179, making it a straightforward swap when replacing a worn or fouled factory plug. As a maintenance item, it is intended for routine spark plug replacement to keep ignition performance consistent and to guard against overheating during sustained heavy-load running.\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 QL78C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChampion Plug Number:\u003c\/strong\u003e 883\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 037551002436\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e Bombardier 502179\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrode Core Material:\u003c\/strong\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 9.35 x 5.51 x 3.07 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eListed as a Tohatsu outboard spark plug and cross-referenced as a direct OEM replacement for Bombardier engines specifying part number 502179.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e502179 (Bombardier)\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Champion QL78C spark plug?\u003c\/strong\u003e It is a marine spark plug with a copper core electrode for increased conductivity and heat control, sold under the Champion designation QL78C and also cataloged as Champion Spark Plug # 883.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the QL78C cross-reference to an OEM number?\u003c\/strong\u003e Yes, the Champion QL78C is a direct OEM cross-reference for Bombardier part number 502179.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs Champion Spark Plug # 883 the same part as the QL78C?\u003c\/strong\u003e Yes, both refer to the same Champion marine spark plug; 883 is the Champion plug number and QL78C is the manufacturer part number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the electrode made of?\u003c\/strong\u003e The QL78C uses a copper core electrode, which provides increased conductivity and heat control for good overall wear.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this spark plug weigh?\u003c\/strong\u003e The Champion QL78C weighs 0.15 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the QL78C spark plug?\u003c\/strong\u003e The Champion QL78C measures 9.35 x 5.51 x 3.07 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Champion QL78C resistant to fouling and corrosion?\u003c\/strong\u003e Yes, the QL78C is designed to resist fouling and offers superior corrosion resistance, which is important in marine environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this plug handle heavy engine loads?\u003c\/strong\u003e The QL78C is designed to resist overheating under heavy engine loads, making it suitable for sustained marine engine use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat engines is the Champion QL78C intended for?\u003c\/strong\u003e The QL78C is listed as a Tohatsu outboard spark plug and is also cross-referenced as an OEM replacement for Bombardier engines calling for part number 502179.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Champion QL78C a genuine OEM part or aftermarket?\u003c\/strong\u003e The Champion QL78C is manufactured by Champion as a quality OEM-type replacement plug, not a generic aftermarket copy.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat UPC is associated with the Champion QL78C?\u003c\/strong\u003e The Champion QL78C carries UPC 037551002436.\u003c\/p\u003e","brand":"Champion Spark Plugs","offers":[{"title":"Default Title","offer_id":49027462824155,"sku":"CHA-QL78C","price":4.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/QL78C__38834.1722504789.500.750_e5c17edf-3846-458d-aa76-3400666aa387.jpg?v=1785329076","url":"https:\/\/www.goodvibesmarina.com\/products\/champion-ql78c-marine-spark-plug-replaces-bombardier-502179","provider":"Good Vibes Marina","version":"1.0","type":"link"}
