{"product_id":"ngk-4322-br8hs-standard-spark-plug-for-mercury-and-mariner-outboards","title":"NGK 4322 BR8HS Standard Spark Plug for Mercury and Mariner Outboards","description":"\u003cp\u003eThe NGK 4322 (type BR8HS) is a Standard series spark plug built on NGK's proven copper-core design, engineered to deliver reliable ignition performance across a wide range of outboard, sterndrive, personal watercraft, and powersport engines. At its core is a solid copper center electrode that offers superior heat dissipation and conductivity, paired with a nickel center electrode tip and a standard nickel ground electrode for consistent, durable sparking. The plug carries a rated resistance of 5000 ohms and uses a standard ground electrode configuration rather than a resistor or projected-tip design.\u003c\/p\u003e\u003cp\u003eNGK treats the shell of this Standard spark plug with corrosion-resistant plating, which eases installation and removal and helps the plug hold up in the marine environment where corrosion is a constant threat. The broad heat range of the design is intended to keep the plug operating in its ideal temperature window across varying loads and engine conditions, supporting steady combustion and consistent starting.\u003c\/p\u003e\u003cp\u003eThe NGK 4322 \/ BR8HS is application-specific to the engines listed by NGK for this part number, including select Mercury and Mariner outboards, Yamaha sterndrive (I\/O), outboard, personal watercraft, snowmobile, and motorcycle engines, plus select Suzuki outboards and other listed powersport applications. Always confirm this is the correct plug for your specific engine using your owner's or service manual before installing, since using the wrong spark plug can reduce performance and 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 4322\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNGK Type Designation:\u003c\/strong\u003e BR8HS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 087295143223\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Mercury Outboard Spark Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround Configuration:\u003c\/strong\u003e Standard Ground\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\u003eGround Electrode Core Material:\u003c\/strong\u003e Nickel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance:\u003c\/strong\u003e 5000 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 3.15 inches L x 0.79 inches H x 1.57 inches W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e China\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1 spark plug\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOutboard (O\/B): Mariner 1994-2001;
