It uses a solid copper core center electrode for strong heat dissipation and conductivity, paired with a nickel center electrode tip and a standard nickel ground electrode for consistent, everyday performance. The insulator is a high-grade ceramic construction that resists flashover and helps prevent cross-threading during installation and removal.\u003c\/p\u003e\u003cp\u003eThis spark plug is treated with a corrosion-resistant plating that keeps the threads turning smoothly during service, reducing the risk of seizing in the cylinder head over time. With an electrical resistance of 5000 ohms and a standard ground configuration, the NGK 4122 (BR7HS) is designed as a straightforward, OE-style replacement plug rather than a performance or racing plug.\u003c\/p\u003e\u003cp\u003eThe NGK 4122 (BR7HS) is used across outboard motors, personal watercraft, motorcycles, and small power equipment engines. On the marine side, it fits a range of Evinrude, Johnson, and Yamaha outboards, along with Yamaha personal watercraft and Yamaha water pump engines, making it a common maintenance item for boat owners replacing worn plugs as part of routine engine service.\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 4122\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNGK Plug Code:\u003c\/strong\u003e BR7HS\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\u003eResistance:\u003c\/strong\u003e 5000 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 14mm\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 087295141229\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1 spark plug\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOutboard: Evinrude (1977-2003), Johnson (1978-2006), Suzuki Spirit (1976-1981), Yamaha (1996-2004)\u003c\/li\u003e\n\u003cli\u003ePersonal Watercraft: Yamaha (1997-2001)\u003c\/li\u003e\n\u003cli\u003eMotorcycle: Aprilia (1993-2005), Honda (1991-1996), Husqvarna (1999-2003), Yamaha (1991-2001)\u003c\/li\u003e\n\u003cli\u003ePower Equipment: Kohler engines, Solo lawnmowers, Yamaha water pumps\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the NGK 4122 spark plug fit?\u003c\/strong\u003e The NGK 4122, also identified by the plug code BR7HS, fits Evinrude outboards from 1977-2003, Johnson outboards from 1978-2006, Yamaha outboards from 1996-2004, Suzuki Spirit outboards from 1976-1981, and Yamaha personal watercraft from 1997-2001, along with a range of motorcycles and power equipment engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the NGK 4122 the same as the BR7HS plug?\u003c\/strong\u003e Yes, 4122 and BR7HS refer to the same NGK standard spark plug;
