It is engineered specifically for marine use, resisting the overheating that can occur under heavy, sustained engine loads on the water. The copper core center electrode allows for accurate control of heat range, helping the plug resist fouling and deliver dependable, proven performance over its service life. Superior corrosion resistance helps the plug hold up in the humid, saltwater-exposed conditions typical of marine engine bays. Champion builds the 871 to ISO and SAE standards, giving boat owners a quality OEM-type replacement plug for scheduled tune-ups and engine maintenance. This plug is cataloged for Evinrude outboard engines, making it a straightforward replacement choice when servicing compatible outboards. Champion identifies this part internally as Spark Plug # 871.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Champion\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 871\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType Designation:\u003c\/strong\u003e RJ8C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChampion Spark Plug Number:\u003c\/strong\u003e 871\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore Material:\u003c\/strong\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShell\/Top Material:\u003c\/strong\u003e Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 037551000562\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Evinrude Outboard Spark Plugs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.15 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eEvinrude outboard engines\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Champion 871 spark plug also known as?\u003c\/strong\u003e The Champion 871 is also identified by its type designation RJ8C, and Champion lists it internally as Spark Plug # 871.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat engines is the Champion 871 (RJ8C) spark plug designed for?\u003c\/strong\u003e This plug is cataloged for Evinrude outboard engines and is built specifically for marine use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Champion 871 resist fouling?\u003c\/strong\u003e Yes, the copper core center electrode in the Champion 871 (RJ8C) allows for accurate control of heat range, which helps the plug resist fouling over its service life.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the center electrode made of?\u003c\/strong\u003e The Champion 871 (RJ8C) uses a copper core center electrode, which increases conductivity and improves heat control compared to a solid electrode.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Champion 871 corrosion resistant?\u003c\/strong\u003e Yes, the Champion 871 (RJ8C) offers superior corrosion resistance, which is important given the humid and saltwater-exposed conditions common in marine engine compartments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the Champion 871 handle heavy engine loads?\u003c\/strong\u003e It is designed to resist overheating under heavy engine loads, which is a key requirement for marine spark plugs that run at sustained high output.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many spark plugs come in one unit?\u003c\/strong\u003e The Champion 871 (RJ8C) is sold as a single spark plug, with a unit count of 1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat standards is the Champion 871 built to?\u003c\/strong\u003e Champion builds the 871 (RJ8C) to ISO and SAE standards for proven performance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Champion 871 spark plug weigh?\u003c\/strong\u003e The Champion 871 (RJ8C) weighs 0.15 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Champion 871 an OEM-type replacement?\u003c\/strong\u003e Yes, the Champion 871 (RJ8C) is a quality OEM-type replacement spark plug intended for marine engine maintenance and tune-ups.\u003c\/p\u003e","brand":"Champion Spark Plugs","offers":[{"title":"Default Title","offer_id":49027463151835,"sku":"CHA-RJ8C","price":3.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/RJ8C__41869.1739460451.500.750.jpg?v=1785163562","url":"https:\/\/www.goodvibesmarina.com\/products\/champion-871-rj8c-marine-spark-plug-copper-core-for-evinrude-outboard-engines","provider":"Good Vibes Marina","version":"1.0","type":"link"}
