Its center electrode uses an iridium tip that NGK rates as six times harder than platinum, giving it a significantly longer service life than a standard copper-tip plug. Supporting that tip is a 98% pure copper core and a high-grade pure alumina ceramic insulator, a combination engineered to prevent the plug from overheating while delivering reliable starts. The ground electrode uses a Standard Ground configuration with a nickel core, and the plug carries a resistance rating of 5000 ohms.\u003c\/p\u003e\u003cp\u003eNGK Laser Iridium plugs are tested to NGK's own quality and durability standards and are sold as an actual OE or equivalent replacement, not a generic substitute. The NGK 4462 is suitable for automotive, motorcycle, and marine engines. As with any spark plug, always check your engine's maintenance manual and use only the plug recommended by your engine's original equipment manufacturer; 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 4462\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNGK Type Number:\u003c\/strong\u003e IZFR6J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance:\u003c\/strong\u003e 5000 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround Configuration:\u003c\/strong\u003e Standard Ground\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 Iridium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 087295176511\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eQuicksilver \/ Mercury 33-843220Q\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between the NGK 4462 and a standard copper spark plug?\u003c\/strong\u003e The NGK 4462 (IZFR6J) uses an iridium-tipped center electrode that NGK rates as six times harder than platinum, giving it longer service life than a standard copper-tip plug, while its 98% pure copper core still handles heat dissipation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the NGK 4462 replace the Quicksilver\/Mercury 33-843220Q spark plug?\u003c\/strong\u003e Yes, the NGK 4462 spark plug (NGK part number IZFR6J) is listed as a replacement for Quicksilver\/Mercury part number 33-843220Q.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the electrical resistance rating of the NGK 4462 spark plug?\u003c\/strong\u003e 5000 ohms is the resistance rating of the NGK 4462 Laser Iridium spark plug.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat materials are used in the NGK 4462 spark plug's electrodes?\u003c\/strong\u003e The NGK 4462 has a copper-core center electrode with an iridium tip, paired with a nickel-core ground electrode in a Standard Ground configuration.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the NGK 4462 spark plug weigh?\u003c\/strong\u003e 0.15 pounds is the weight of the NGK 4462 Laser Iridium spark plug.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the NGK 4462 a genuine NGK part or an aftermarket equivalent?\u003c\/strong\u003e It is a genuine NGK Laser Iridium spark plug, sold under NGK's own designation IZFR6J (stock number 4462), and is tested to NGK's quality and durability standards as an actual OE or equivalent replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat ground electrode configuration does the NGK 4462 use?\u003c\/strong\u003e Standard Ground configuration is used on the NGK 4462 Laser Iridium spark plug, with a nickel-core ground electrode.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the NGK 4462 be used in automotive, motorcycle, and marine engines?\u003c\/strong\u003e Yes, the NGK 4462 (IZFR6J) Laser Iridium spark plug is built for use in automotive, motorcycle, and marine engines, provided it matches your engine manufacturer's specified plug.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if the NGK 4462 is the correct spark plug for my engine?\u003c\/strong\u003e Check your engine's maintenance manual for the correct spark plug specification;
