NGK's Standard line is engineered as an OE cornerstone, delivering the same construction and reliability that has backed original-equipment ignition systems for decades. The plug uses a standard ground electrode configuration with a nickel ground electrode, a copper core center electrode with a nickel tip, and a ceramic insulator over a 14 millimeter thread. A 5000 ohm resistor is built in to suppress ignition interference, and the shell and threads carry a corrosion-resistant plating that keeps installation and removal easy even after extended service.\u003c\/p\u003e\u003cp\u003eThe NGK BR8ES is application-specific, so confirm your engine's plug requirement in its owner's or maintenance manual before ordering, and only install the plug type recommended by the original equipment manufacturer. Using an incorrect 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 5422\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNGK Part Number:\u003c\/strong\u003e BR8ES\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\u003eThread Size:\u003c\/strong\u003e 14 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 087295154229\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\u003ePorsche 911, model years 1971-70, 1968\u003c\/li\u003e\n\u003cli\u003eRenault Fuego, model years 1984-82\u003c\/li\u003e\n\u003cli\u003eRenault R17, model years 1974-73\u003c\/li\u003e\n\u003cli\u003eMotorcycle - Aprilia, model years 2006-96\u003c\/li\u003e\n\u003cli\u003eMotorcycle - Gas Gas, model years 2005-97\u003c\/li\u003e\n\u003cli\u003eMotorcycle - Honda, model year 1990\u003c\/li\u003e\n\u003cli\u003eMotorcycle - Kawasaki, model years 2005-83\u003c\/li\u003e\n\u003cli\u003eMotorcycle - KTM, model year 2006\u003c\/li\u003e\n\u003cli\u003eMotorcycle - Moto Guzzi, model years 2006-04\u003c\/li\u003e\n\u003cli\u003eMotorcycle - Yamaha, model years 1985-83\u003c\/li\u003e\n\u003cli\u003eSnowmobile - Arctic Cat, model years 1990-74\u003c\/li\u003e\n\u003cli\u003eSnowmobile - Moto-Ski, model years 1979-73\u003c\/li\u003e\n\u003cli\u003eSnowmobile - Ski-Doo, model years 1978-73\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003eNo OEM cross-reference numbers are listed for the NGK BR8ES (5422).\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the NGK 5422 spark plug?\u003c\/strong\u003e The NGK 5422 is the stock number for NGK's BR8ES Standard spark plug, built with a solid copper core, a nickel-tipped center electrode, and a standard ground electrode configuration.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the NGK BR8ES the same as NGK stock number 5422?\u003c\/strong\u003e Yes, NGK 5422 and NGK BR8ES refer to the same Standard spark plug;
