It uses a V-cut center electrode paired with a concave ground electrode to increase ignitability and deliver more complete combustion compared to a standard nickel plug. The center electrode has a copper core with a nickel tip for strong heat dissipation and reliable starts, while the ceramic insulator provides consistent heat resistance during operation. Trivalent metal plating on the shell eliminates the need to apply anti-seize compound before installation, and cold-rolled threads help prevent cross-threading into the cylinder head.\u003c\/p\u003e\u003cp\u003eThe NGK YR5 (7052) is built with a 5000 ohm resistor design for ignition interference suppression and a standard ground electrode configuration. It is intended for marine I\/O applications including Berkeley, Flagship, Hardin, and OMC drives, as well as GM-based Buick, Chevrolet, GMC, and Pontiac engines used in marine and industrial service, plus farm tractors and lift trucks that share the same ignition specification. Always confirm the correct plug against your engine's maintenance manual before ordering, 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
