Part number 933M, the QL86 runs one heat range hotter than the QL82C — helping to burn off carbon deposits and maintain a clean electrode on engines that don't generate enough heat to self-clean a cooler plug.\u003c\/p\u003e\u003cp\u003eThe C-suffix indicates a non-resistor design with a copper core electrode, making it the correct choice for engines that specifically require a non-resistor plug. The QL-series long-reach thread is engineered for outboard combustion chambers requiring deeper plug engagement. Sold in a 4-pack (Champion part 12214). 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 QL86C marine spark plug — 4-pack (Champion #933M)\u003c\/li\u003e\n\u003cli\u003eHotter heat range than the QL82C — suited for cooler-running or lower-RPM 2-stroke outboard applications\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\u003c\/ul\u003e\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEvinrude and Johnson 2-stroke outboard engines specifying Champion QL86C or equivalent\u003c\/li\u003e\n\u003cli\u003eCooler-running or lower-average-RPM 2-stroke outboard engines where a hotter plug is specified\u003c\/li\u003e\n\u003cli\u003eLong-reach, non-resistor 2-stroke applications cross-referencing Champion #933M or part 12214\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 QL86C is the hotter alternative to the \u003ca href=\"\/products\/champion-ql82c-marine-spark-plug-931m-4-pack-long-reach-2-stroke-outboard-24-ql82c\"\u003eChampion QL82C #931M\u003c\/a\u003e in the non-resistor long-reach family. A hotter plug is appropriate when your engine runs cool — typically lower-horsepower or trolling-speed applications — and you're seeing carbon fouling on the electrode. If your engine specifies the QL86C, use the QL86C; don't substitute a cooler plug thinking it's safer, as a plug that's too cold will foul quickly.\u003c\/p\u003e\u003cp\u003eIf your engine requires a resistor plug in this heat range, check the \u003ca href=\"\/products\/champion-ql82yc-marine-spark-plug-932m-4-pack-long-reach-2-stroke-outboard-24-ql82yc\"\u003eChampion QL82YC #932M\u003c\/a\u003e.
