Manufactured by NGK Spark Plugs, this iridium spark plug uses a fine-wire center electrode to promote reliable spark formation while reducing the voltage required from the ignition system. The result is efficient combustion, consistent starting, and dependable operation across a wide range of riding and operating conditions.\u003c\/p\u003e\u003cp\u003eThe iridium electrode is approximately 25% smaller than a platinum electrode and about one-quarter the size of a conventional nickel electrode. This ultra-small diameter helps focus the spark and may reduce strain on ignition components, supporting longer ignition-system service life. The CR8EIB-10 design is intended as a direct replacement for applications that specify this plug configuration and heat range. Always verify the vehicle manufacturer’s application guide, thread specification, reach, heat range, and gap requirements before installation.\u003c\/p\u003e\u003cp\u003eA newly engineered metal shell plating provides enhanced resistance to corrosion, helping protect the plug in demanding environments and simplify future removal. The NGK Spark Plugs Iridium IX CR8EIB-10 is supplied under manufacturer part number 4948 and vendor part number 4948. It is a practical replacement choice for restoring proper ignition performance and maintaining the fit and function specified by the original equipment application.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrand: NGK Spark Plugs\u003c\/li\u003e\n\u003cli\u003eProduct line: Iridium IX\u003c\/li\u003e\n\u003cli\u003eModel: CR8EIB-10\u003c\/li\u003e\n\u003cli\u003eManufacturer part number: 4948\u003c\/li\u003e\n\u003cli\u003eVendor part number: 4948\u003c\/li\u003e\n\u003cli\u003eElectrode material: Iridium\u003c\/li\u003e\n\u003cli\u003eFine-wire center electrode: Requires less voltage and supports reliable ignition\u003c\/li\u003e\n\u003cli\u003eIgnition-system support: Reduced voltage demand may help extend ignition component life\u003c\/li\u003e\n\u003cli\u003eShell plating: Enhanced anti-corrosion protection\u003c\/li\u003e\n\u003cli\u003eFitment: Compatible with applications specifying the NGK CR8EIB-10 spark plug; verify vehicle-specific requirements before installation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NGK SPARK PLUGS","offers":[{"title":"Default Title","offer_id":67567710535915,"sku":"21030034","price":16.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/24069.png?v=1790797765","url":"https:\/\/ctracingservices.com\/products\/ngk-spark-plugs-iridium-ix-cr8eib-10-spark-plug-part-number-4948","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
