Built specifically for the demands of marine use, this spark plug is designed to resist overheating under heavy engine loads, a condition that standard automotive plugs are not built to withstand. The copper core center electrode delivers increased conductivity and precise heat range control, giving the plug good overall wear characteristics and a longer service life.\u003c\/p\u003e\u003cp\u003eCorrosion resistance is a priority in the marine environment, and the Champion CCH942M addresses this with a shell construction that resists fouling and helps the plug perform dependably over time. It is built to ISO and SAE standards, giving boat owners a proven, standardized level of performance and fit. At 0.15 pounds, it is a lightweight, easy-to-handle replacement part that keeps routine engine maintenance simple.\u003c\/p\u003e\u003cp\u003eThis spark plug is categorized for Mercruiser marine engines and is intended as a direct, dependable replacement during scheduled tune-ups or when diagnosing ignition issues such as misfires, hard starting, or rough idle. Its corrosion-resistant shell and copper core construction make it well suited to the moisture and heavy-load conditions typical of marine applications.\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 CCH942M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference Number:\u003c\/strong\u003e 942M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore Material:\u003c\/strong\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Mercruiser Spark Plugs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 037551007004\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\u003eDesigned for Mercruiser marine engines\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e942M\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Champion CCH942M spark plug used for?\u003c\/strong\u003e The Champion CCH942M is a copper core marine spark plug categorized for Mercruiser marine engines, used as a direct OEM replacement during routine tune-ups or ignition troubleshooting.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the CCH942M the same as the Champion 942M spark plug?\u003c\/strong\u003e Yes, the Champion CCH942M carries the OEM cross reference number 942M, so it is the equivalent to that Champion spark plug designation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the electrode made of?\u003c\/strong\u003e The CCH942M has a copper core center electrode, which allows for accurate control of heat range and delivers increased conductivity for good overall wear.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this spark plug resist corrosion in a marine environment?\u003c\/strong\u003e Yes, the Champion CCH942M is built with superior corrosion resistance and is designed to resist fouling, which suits the moisture exposure common in marine engine applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Champion CCH942M weigh?\u003c\/strong\u003e This spark plug weighs 0.15 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the CCH942M meet any industry standards?\u003c\/strong\u003e The Champion CCH942M is built to ISO and SAE standards for proven, standardized performance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this spark plug handle heavy engine loads without overheating?\u003c\/strong\u003e Yes, the Champion CCH942M is specifically designed to resist overheating under heavy engine loads, which is a key requirement for marine engine operation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many spark plugs come in one purchase?\u003c\/strong\u003e The Champion CCH942M is sold as a single unit, with a unit count of 1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat engines is the Champion CCH942M spark plug categorized for?\u003c\/strong\u003e The Champion CCH942M is categorized under Mercruiser spark plugs for Mercruiser marine engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy choose a copper core spark plug over other types for a marine engine?\u003c\/strong\u003e A copper core electrode, as used in the Champion CCH942M, provides increased conductivity and more accurate heat range control, which contributes to good overall wear and dependable performance under marine operating conditions.\u003c\/p\u003e","brand":"Champion Spark Plugs","offers":[{"title":"Default Title","offer_id":49027463512283,"sku":"CHA-RV91MC","price":3.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/RV91MC__11943.1722369965.500.750.jpg?v=1785163565","url":"https:\/\/www.goodvibesmarina.com\/products\/champion-cch942m-marine-spark-plug-for-mercruiser-engines-copper-core-oem-equivalent-942m","provider":"Good Vibes Marina","version":"1.0","type":"link"}
