Part number 3481, the DCPR6E is commonly specified for Honda and Yamaha 4-stroke outboard engines that use the smaller 12mm thread format — a design that allows for more compact combustion chamber geometry without sacrificing ignition performance.\u003c\/p\u003e\u003cp\u003eThe projected tip improves ignitability and combustion efficiency, while the built-in resistor suppresses radio frequency interference — important in the marine environment where VHF radios, GPS, and chartplotters are in close proximity to the engine. NGK's triple gasket sealing process eliminates combustion gas leakage, and cold-rolled threads protect the cylinder head on installation.\u003c\/p\u003e\u003cp\u003eSold in a 4-pack. Always verify fitment against your engine's owner's manual or NGK application guide before ordering.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eNGK DCPR6E spark plug — 4-pack (NGK #3481)\u003c\/li\u003e\n\u003cli\u003eD-series compact 12mm thread — for engines requiring a smaller-diameter plug\u003c\/li\u003e\n\u003cli\u003eProjected tip for improved ignitability and combustion efficiency\u003c\/li\u003e\n\u003cli\u003eBuilt-in resistor suppresses radio frequency interference (RFI)\u003c\/li\u003e\n\u003cli\u003eSolid copper core for reliable heat transfer and consistent spark\u003c\/li\u003e\n\u003cli\u003eTriple gasket sealing eliminates combustion gas leakage past the shell\u003c\/li\u003e\n\u003cli\u003eCold-rolled threads protect cylinder head threads on installation\u003c\/li\u003e\n\u003cli\u003eTrivalent plating (silver chromate and zinc) for corrosion resistance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHonda 4-stroke outboard engines specifying NGK DCPR6E or equivalent\u003c\/li\u003e\n\u003cli\u003eYamaha 4-stroke outboard engines specifying NGK DCPR6E or equivalent\u003c\/li\u003e\n\u003cli\u003eOther 4-stroke engines requiring a compact 12mm resistor plug cross-referencing NGK #3481\u003c\/li\u003e\n\u003cli\u003eVerify fitment using your engine's owner's manual or the NGK spark plug application guide\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eThe DCPR6E is the correct plug for Honda and Yamaha 4-stroke outboards that specify the compact 12mm D-series thread — don't substitute a standard 14mm plug, as the thread diameter is not interchangeable. If you're doing a full outboard tune-up, replace all plugs at the same time and inspect the old plugs for fouling or wear patterns that might indicate a fuel mixture or oil issue worth addressing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e This product currently has no image on file.
