It uses a solid copper core in the center electrode for superior heat dissipation and conductivity, paired with a nickel-plated ground electrode and center electrode tip. This corrosion-resistant plating keeps threads and electrodes protected in service and makes the plug easier to install and remove during routine maintenance. The plug has a Standard ground electrode configuration and measures 5000 ohm resistance for suppression of ignition noise.\u003c\/p\u003e\u003cp\u003eThis plug is designated for a range of outboard, ATV, and motorcycle applications, including Mercury and Mariner outboard motors and Yamaha outboards, as well as select Honda, Kawasaki, and Suzuki powersport engines. Always check your engine and maintenance manual to confirm the DPR6EA-9 is the correct plug for your specific engine, since installing 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 5531\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNGK Part Number:\u003c\/strong\u003e DPR6EA-9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 087295155318\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance:\u003c\/strong\u003e 5000 Ohm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround Configuration:\u003c\/strong\u003e Standard\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\u003eInsulator Material:\u003c\/strong\u003e Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1 spark plug per pack\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\n\u003cli\u003eOutboard -
