Part number 931M, the C-suffix design uses a copper core electrode for reliable heat transfer and consistent spark — without the built-in resistor found in YC or JC4 series plugs. This makes it the correct choice for engines that specifically require a non-resistor plug, as specified in the engine's owner's manual.\u003c\/p\u003e\u003cp\u003eThe QL-series long-reach thread is engineered for outboard combustion chambers requiring deeper plug engagement. Sold in a 4-pack (Champion part 12212). Always verify fitment against your engine's owner's manual or Champion application guide before ordering.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eChampion QL82C marine spark plug — 4-pack (Champion #931M)\u003c\/li\u003e\n\u003cli\u003eLong-reach QL-series thread — for outboard engines requiring deeper plug engagement\u003c\/li\u003e\n\u003cli\u003eNon-resistor design — for engines that specifically require a non-resistor spark plug\u003c\/li\u003e\n\u003cli\u003eCopper core electrode for reliable heat transfer and consistent spark\u003c\/li\u003e\n\u003cli\u003eDesigned for 2-stroke marine outboard applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEvinrude and Johnson 2-stroke outboard engines specifying Champion QL82C or equivalent\u003c\/li\u003e\n\u003cli\u003eOther 2-stroke marine outboard engines requiring a long-reach, non-resistor plug\u003c\/li\u003e\n\u003cli\u003eAny application cross-referencing Champion #931M or part 12212\u003c\/li\u003e\n\u003cli\u003eVerify fitment using your engine's owner's manual or the Champion spark plug application guide\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eThe QL82C is the right plug when your engine's manual specifically calls for a non-resistor, long-reach plug. Using a resistor plug (like the QL78YC) in an engine that specifies a non-resistor plug can cause ignition misfires on some older 2-stroke systems — so it's worth confirming the spec before substituting. If you're unsure whether your engine requires a resistor or non-resistor plug, check the owner's manual or the Champion application guide.\u003c\/p\u003e\u003cp\u003eFor long-reach 4-stroke outboard applications, see the \u003ca href=\"\/products\/champion-ql78yc-marine-spark-plug-938m-4-pack-long-reach-4-stroke-outboard-24-ql78yc\"\u003eChampion QL78YC #938M\u003c\/a\u003e or the \u003ca href=\"\/products\/champion-ql77jc4-marine-spark-plug-828m-4-pack-mercury-4-stroke-24-ql77jc4\"\u003eChampion QL77JC4 #828M\u003c\/a\u003e.
