Champion Spark Plug #322 uses a copper core center electrode that allows for accurate control of heat range, giving the plug longer service life and steady conductivity under load. The shell carries Champion's patented TinTac and ULTRASEAL coating for maximum corrosion resistance, an important feature in the salt and moisture exposure common to marine environments. A patented SAC-9 semiconductor is built into the plug for maximum EMI and RFI suppression, helping reduce electrical interference with onboard electronics. The RN11YC4 is built to ISO and SAE standards for proven, consistent performance.\u003c\/p\u003e\u003cp\u003eThis spark plug fits Honda BF5 OHV 4-Stroke 5HP and Honda BF50 OHV 4-Stroke 5HP outboard engines. It is sold as a single spark plug with a 14mm x 1.25mm thread and a copper core electrode construction.\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 CCH322\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChampion Spark Plug Number:\u003c\/strong\u003e 322\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct MPN:\u003c\/strong\u003e RN11YC4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 037551000388\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore Material:\u003c\/strong\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 14mm x 1.25mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShell Material:\u003c\/strong\u003e Metal, TinTac and ULTRASEAL coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1 spark plug\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHonda BF5 OHV, 4-Stroke, 5 HP\u003c\/li\u003e\n\u003cli\u003eHonda BF50 OHV, 4-Stroke, 5 HP\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Champion RN11YC4 (part 322) fit?\u003c\/strong\u003e The Champion RN11YC4 spark plug, Champion Spark Plug #322, fits Honda BF5 OHV 4-Stroke 5HP and Honda BF50 OHV 4-Stroke 5HP outboard engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a copper spark plug?\u003c\/strong\u003e Yes, the RN11YC4 uses a copper core center electrode, which allows for accurate control of heat range and provides longer plug life along with good conductivity.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat thread size does the Champion RN11YC4 use?\u003c\/strong\u003e This spark plug has a 14mm x 1.25mm thread size.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many spark plugs come in a pack?\u003c\/strong\u003e The Champion RN11YC4 (Champion #322) is sold as a single spark plug, one per pack.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this spark plug resist corrosion in a marine environment?\u003c\/strong\u003e Yes, the RN11YC4 shell is coated with Champion's patented TinTac and ULTRASEAL coating for maximum corrosion resistance, which suits saltwater and marine use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between the Champion RN11YC4 and a standard automotive spark plug?\u003c\/strong\u003e The RN11YC4 is part of Champion's Copper Plus marine line, built with the TinTac and ULTRASEAL corrosion-resistant coating and a SAC-9 semiconductor for EMI and RFI suppression, features aimed at marine engine operating conditions rather than general automotive use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does the SAC-9 semiconductor do on this spark plug?\u003c\/strong\u003e The SAC-9 semiconductor in the Champion RN11YC4 provides maximum EMI and RFI suppression, reducing electrical interference from the ignition system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Champion RN11YC4 spark plug weigh?\u003c\/strong\u003e The Champion RN11YC4 (part CCH322) weighs 0.15 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Champion RN11YC4 built to any recognized standard?\u003c\/strong\u003e Yes, this spark plug is built to ISO and SAE standards for proven performance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is Champion Spark Plug number 322?\u003c\/strong\u003e Champion Spark Plug #322 is the manufacturer's internal number for the RN11YC4 Copper Plus Marine Spark Plug.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the electrode core made of?\u003c\/strong\u003e The center electrode core on the RN11YC4 is copper, chosen for its conductivity and heat control properties.\u003c\/p\u003e","brand":"Champion Spark Plugs","offers":[{"title":"Default Title","offer_id":49027463184603,"sku":"CHA-RN11YC4","price":2.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/RN11YC4__35561.1739459071.500.750.jpg?v=1785163562","url":"https:\/\/www.goodvibesmarina.com\/products\/champion-rn11yc4-copper-plus-marine-spark-plug-for-honda-bf5-and-bf50-5hp-outboards","provider":"Good Vibes Marina","version":"1.0","type":"link"}
