Non-Resistor Marine Spark Plug for 2-Stroke Outboards — 8-Pack.
The Champion RJ8C is a standard-reach, non-resistor marine spark plug designed for 2-stroke outboard engines and small 2-stroke marine engines. Part number 871, the C-suffix design uses a copper core electrode for reliable heat transfer and consistent spark — without a built-in resistor, making it the correct choice for engines that specifically require a non-resistor plug.
Sold in an 8-pack — a convenient quantity for servicing larger multi-cylinder 2-stroke outboards or stocking up for the season. Always verify fitment against your engine's owner's manual or Champion application guide before ordering.

Parts Desk Insights
The RJ8C is a high-volume 2-stroke outboard plug — the 8-pack format makes it practical for servicing 6-cylinder or V6 2-stroke outboards in a single purchase, or for keeping a full set on hand for the season. As with all non-resistor plugs, confirm your engine's manual specifies a non-resistor plug before ordering — using a resistor plug in a non-resistor application (or vice versa) can cause ignition issues on some older 2-stroke systems.
For a resistor version in a similar application, see the Champion RJ14YC #63. For long-reach 2-stroke outboard plugs, see the Champion QL82C #931M or Champion QL86C #933M. For standard-reach 2-stroke plugs, see the Champion L76V #827M.
