It is engineered for dependable ignition performance in marine engines that see heavy, sustained loads, where overheating and fouling are common failure points for lower-grade plugs. This spark plug is a quality OEM-style replacement, not a generic aftermarket substitute.\u003c\/p\u003e\u003cp\u003eAt the core of the CCH406 is a copper center electrode, which conducts heat and current more efficiently than solid steel or nickel-alloy designs, allowing for accurate control of heat range and longer service life. The shell is treated with Champion's patented TinTac and ULTRASEAL coatings, which provide maximum corrosion resistance against the moisture and salt exposure typical of marine environments. A patented SAC-9 semiconductor is built into the plug to suppress electromagnetic (EMI) and radio-frequency (RFI) interference, helping protect onboard electronics and marine radios from ignition noise. Every CCH406 plug is manufactured to ISO and SAE standards for consistent, proven performance.\u003c\/p\u003e\u003cp\u003eThe CCH406 is listed under Champion's Chrysler inboard marine engine spark plug line, and the same RV12YC design has also been used as Champion part 406 in 1970-1997 Chevrolet C1500 and Chevrolet K1500 trucks, giving it a broad, well-documented cross-application history.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
