Long-Reach Marine Spark Plug for 2-Stroke Outboards — 4-Pack.
The Champion QL16V is a long-reach, projected-tip marine spark plug designed for 2-stroke outboard engines that require a longer thread engagement than standard L-series plugs. Part number 876M, the QL-series features a copper core electrode for reliable heat transfer and consistent spark, with a projected tip that improves ignitability in the combustion chamber.
Sold in a 4-pack (Champion part 12204). Always verify fitment against your engine's owner's manual or Champion application guide before ordering — using the wrong reach plug can cause engine damage.

Parts Desk Insights
The QL16V is the long-reach version of the L-series marine plugs — if your engine specifies a QL-series plug, it's critical to use the correct reach. Installing a short-reach plug in a long-reach application leaves threads exposed in the combustion chamber, which can cause carbon buildup, plug fouling, and in severe cases, engine damage. Always match the plug series to your engine's specification.
