Part number 810, the RA8HC features 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.\u003c\/p\u003e\u003cp\u003eSold in a 4-pack (Champion part 10388).

If your engine manual calls for an RA8HC, this is the correct part — the short reach and non-resistor design are both engine-specific requirements that shouldn't be substituted without confirming compatibility. Using a long-reach plug in a short-reach application can cause piston contact and serious engine damage.\u003c\/p\u003e\u003cp\u003eFor long-reach 2-stroke outboard plugs, see 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 or \u003ca href=\"\/products\/champion-ql86c-marine-spark-plug-933m-4-pack-long-reach-2-stroke-outboard-24-ql86c\"\u003eChampion QL86C #933M\u003c\/a\u003e.
