It uses a solid copper core center electrode that delivers superior heat dissipation, strong conductivity, and a broad heat range, backed by a corrosion-resistant plating that keeps installation and removal easy over the life of the engine. The ground electrode uses a surface discharge configuration, and the plug is rated at 5,000 ohms of resistance to help suppress ignition interference. Electrode construction pairs a nickel ground electrode core with a copper center electrode core and a nickel center electrode tip, giving the plug durable, consistent sparking across duty cycles.\u003c\/p\u003e\u003cp\u003eThis plug is classified for use in Johnson outboard engines and is built to the same 12 mm thread with a gasket seat design and 0.749 inch reach found on the OE application it replaces, so fit and seating match factory specifications. As part of NGK's Standard plug lineup, the DCPR6E is positioned as an OE cornerstone plug rather than a premium precious-metal upgrade, giving boaters a dependable, factory-grade replacement. Always check your engine's maintenance manual to confirm the DCPR6E, stock number 3481, is the correct plug for your specific powerhead before ordering, since using the wrong plug can reduce performance, hurt fuel economy, or damage the engine.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e NGK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 3481\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNGK Plug Designation:\u003c\/strong\u003e DCPR6E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 087295134818\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround Configuration:\u003c\/strong\u003e Surface Discharge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround Electrode Core Material:\u003c\/strong\u003e Nickel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Electrode Core Material:\u003c\/strong\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Electrode Tip Material:\u003c\/strong\u003e Nickel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance:\u003c\/strong\u003e 5,000 Ohm (Resistor Type)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach:\u003c\/strong\u003e 0.749 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat Type:\u003c\/strong\u003e Gasket Seat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGap Size:\u003c\/strong\u003e 0.04 inches\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\u003cp\u003eClassified for use in Johnson outboard engines requiring a 12 mm, gasket-seat spark plug to this specification.
