This resistor-type spark plug uses a pure alumina silicate ceramic insulator that delivers excellent mechanical strength and efficient heat transfer, helping support consistent operation under demanding conditions. The BR9ES model is identified by NGK Spark Plugs manufacturer part number 5722 and vendor part number BR9ES.\u003c\/p\u003e\u003cp\u003eTrivalent metal plating provides enhanced resistance to corrosion and helps reduce seizing during installation or removal. A copper-core design improves heat removal, while triple sealing helps prevent combustion-gas leakage. Corrugated insulator ribs also help prevent flashover, supporting reliable spark delivery and stable engine performance. For proper fitment, verify that the NGK BR9ES specification and heat range match the original spark plug recommended for your engine or equipment.\u003c\/p\u003e\u003cp\u003eInstall the NGK Spark Plugs BR9ES according to the equipment manufacturer’s service instructions, including the specified gap and tightening procedure. This spark plug is supplied as a single replacement component and is intended for applications calling for the BR9ES model or NGK part number 5722. Always confirm thread, reach, heat range, and ignition-system compatibility before installation.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eModel: BR9ES resistor spark plug\u003c\/li\u003e\n\u003cli\u003eBrand: NGK Spark Plugs\u003c\/li\u003e\n\u003cli\u003eManufacturer Part Number: 5722\u003c\/li\u003e\n\u003cli\u003eVendor Part Number: BR9ES\u003c\/li\u003e\n\u003cli\u003eCeramic Insulator: Pure alumina silicate construction provides strength and efficient heat transfer\u003c\/li\u003e\n\u003cli\u003eCorrosion Protection: Trivalent metal plating helps resist corrosion and seizing\u003c\/li\u003e\n\u003cli\u003eHeat Removal: Copper core supports effective heat dissipation\u003c\/li\u003e\n\u003cli\u003eLeakage Prevention: Triple seals help prevent combustion-gas leakage\u003c\/li\u003e\n\u003cli\u003eFlashover Protection: Corrugated ribs help reduce the risk of flashover\u003c\/li\u003e\n\u003cli\u003eFitment: For compatible engines and equipment requiring the NGK BR9ES specification\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NGK SPARK PLUGS","offers":[{"title":"Default Title","offer_id":67569376329963,"sku":"BR9ES","price":4.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/28548.png?v=1790804470","url":"https:\/\/ctracingservices.com\/products\/ngk-spark-plugs-br9es-spark-plug-part-number-5722","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
