The plug carries a corrosion-resistant plating that makes installation and removal easier over the life of the engine, and it uses a nickel ground electrode with a nickel center electrode tip backed by a copper core, giving it steady, consistent firing performance. A 5000 ohm resistor design helps suppress electrical interference from the ignition system. NGK's Standard line has served as an OE-level cornerstone plug for decades, making the 5722 a straightforward, dependable replacement rather than a specialty performance upgrade.\u003c\/p\u003e\u003cp\u003eThe 5722 is intended for small-engine applications rather than automotive use, with confirmed fitment across ATV, motorcycle, and snowmobile platforms as listed below. Always confirm the correct plug against your engine's owner or service manual before installing, since using 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 5722\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNGK Plug Designation:\u003c\/strong\u003e BR9ES\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 Nickel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulator Material:\u003c\/strong\u003e Ceramic (alumina silicate)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e M14x1.25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGap Size:\u003c\/strong\u003e 0.03 inches\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 087295157220\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eATV: Honda (1982-1988)\u003c\/li\u003e\n\u003cli\u003eMotorcycle: Aprilia (2000-2006)\u003c\/li\u003e\n\u003cli\u003eMotorcycle: Gas Gas (2001)\u003c\/li\u003e\n\u003cli\u003eMotorcycle: Honda (1983-1985)\u003c\/li\u003e\n\u003cli\u003eMotorcycle: KTM (1996-2004)\u003c\/li\u003e\n\u003cli\u003eMotorcycle: Yamaha (1983)\u003c\/li\u003e\n\u003cli\u003eSnowmobile: Arctic Cat (1973-1997)\u003c\/li\u003e\n\u003cli\u003eSnowmobile: John Deere (1981-1982)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHonda 9807959816\u003c\/li\u003e\n\u003cli\u003eHonda 9807959847\u003c\/li\u003e\n\u003cli\u003eHonda 9807959876\u003c\/li\u003e\n\u003cli\u003ePiaggio AP8206915\u003c\/li\u003e\n\u003cli\u003ePorsche 99917001490\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the NGK 5722 spark plug?\u003c\/strong\u003e The NGK 5722 is a Standard series spark plug, identified by NGK as the BR9ES, built with a copper core and nickel electrodes for reliable ignition performance in small engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the NGK 5722 fit outboard motors?\u003c\/strong\u003e Confirmed fitment for the NGK 5722 (BR9ES) covers ATV, motorcycle, and snowmobile applications from Honda, Aprilia, Gas Gas, KTM, Yamaha, Arctic Cat, and John Deere;
