Identified by Champion as spark plug number 825 and cataloged under the Champion J4C designation, this plug is engineered for outboard engine use where consistent conductivity and resistance to fouling matter most. The copper core electrode improves conductivity and heat transfer, helping the plug wear evenly under sustained engine loads instead of overheating or fouling prematurely.\u003c\/p\u003e\u003cp\u003eChampion builds the CCH825 with corrosion-resistant construction to stand up to the humid, saltwater-exposed conditions common to marine engine compartments. It is designed as a straightforward OEM-type replacement, so it installs using standard spark plug service procedures without special tools. Each package contains one spark plug.\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 CCH825\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChampion Spark Plug Number:\u003c\/strong\u003e 825\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrode Material:\u003c\/strong\u003e Copper core\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 037551000012\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1 spark plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Equivalent Part Numbers:\u003c\/strong\u003e 378101, 502193, 509929\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e378101\u003c\/li\u003e\n\u003cli\u003e502193\u003c\/li\u003e\n\u003cli\u003e509929\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Champion CCH825 spark plug replace?\u003c\/strong\u003e The Champion CCH825 spark plug cross-references to OEM part numbers 378101, 502193, and 509929, so any of those OEM numbers point to this same plug.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the CCH825 the same as Champion spark plug 825?\u003c\/strong\u003e Yes, the Champion CCH825 is Champion's own spark plug number 825, also known by the Champion J4C designation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the electrode made of on the Champion CCH825?\u003c\/strong\u003e It uses a copper core center electrode, which improves conductivity and gives more accurate control of heat range for even wear over the plug's life.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many spark plugs come in a CCH825 package?\u003c\/strong\u003e One Champion CCH825 spark plug is included per package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Champion CCH825 spark plug weigh?\u003c\/strong\u003e The Champion CCH825 weighs 0.15 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Champion CCH825 resist fouling and corrosion?\u003c\/strong\u003e Yes, the CCH825 is built to resist fouling and offers corrosion resistance suited to marine engine environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat engine application is the Champion CCH825 designed for?\u003c\/strong\u003e The Champion CCH825 is designated for outboard engine use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Champion CCH825 a genuine OEM part or aftermarket equivalent?\u003c\/strong\u003e The CCH825 is manufactured by Champion as a quality OEM-type replacement spark plug, not a generic aftermarket copy.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat UPC is associated with the Champion CCH825?\u003c\/strong\u003e The Champion CCH825 spark plug carries UPC 037551000012.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I install the Champion CCH825 myself?\u003c\/strong\u003e Yes, the CCH825 installs using standard spark plug replacement procedures and does not require special tools.\u003c\/p\u003e","brand":"Champion Spark Plugs","offers":[{"title":"Default Title","offer_id":49027462332635,"sku":"CHA-J4C","price":2.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/J4C__18306.1739459002.500.750.jpg?v=1785163548","url":"https:\/\/www.goodvibesmarina.com\/products\/champion-cch825-marine-spark-plug-j4c-copper-core-cross-reference-378101-502193-509929","provider":"Good Vibes Marina","version":"1.0","type":"link"}
