Manufactured by NGK Spark Plugs, this premium spark plug uses an iridium center electrode that is 25% smaller than a platinum electrode and approximately one-quarter the size of a conventional nickel electrode.\u003c\/p\u003e\u003cp\u003eThe ultra-small diameter center electrode requires less voltage to create a strong spark, helping reduce the load on the ignition system while supporting consistent engine operation. Its fine-wire design promotes reliable starts, smooth performance, and efficient fuel combustion when properly matched to the vehicle’s engine requirements. The NGK Iridium IX series is engineered for drivers seeking durable replacement spark plugs with advanced electrode technology.\u003c\/p\u003e\u003cp\u003eA newly designed metal shell plating provides enhanced resistance to corrosion, helping protect the spark plug in demanding operating environments and supporting easier removal during future service. This LKAR6AIX-11 model is identified by NGK manufacturer and vendor part number 91187. Confirm the vehicle’s year, make, model, engine, and original equipment specifications before installation to verify fitment, reach, heat range, and gap requirements.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eIridium Electrode: Provides advanced spark plug technology for reliable ignition and long service life.\u003c\/li\u003e\n\u003cli\u003eFine-Wire Center Electrode: Uses an electrode approximately 25% smaller than platinum and one-quarter the size of conventional nickel designs.\u003c\/li\u003e\n\u003cli\u003eReduced Voltage Requirement: Helps create a strong spark with less voltage, reducing ignition system demand.\u003c\/li\u003e\n\u003cli\u003eIgnition System Support: Promotes efficient operation and may help extend ignition component life.\u003c\/li\u003e\n\u003cli\u003eCorrosion-Resistant Shell: Enhanced metal shell plating helps protect against corrosion and supports easier servicing.\u003c\/li\u003e\n\u003cli\u003eApplication Fitment: Designed for compatible vehicles using the NGK LKAR6AIX-11 spark plug specification.\u003c\/li\u003e\n\u003cli\u003eBrand: NGK Spark Plugs.\u003c\/li\u003e\n\u003cli\u003eManufacturer Part Number: 91187.\u003c\/li\u003e\n\u003cli\u003eVendor Part Number: 91187.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NGK SPARK PLUGS","offers":[{"title":"Default Title","offer_id":67568003940587,"sku":"21030524","price":14.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/2300058.png?v=1790799974","url":"https:\/\/ctracingservices.com\/products\/ngk-spark-plugs-iridium-ix-lkar6aix-11-spark-plug-part-number-91187","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
