{"product_id":"lfr6aix-11-iridium-ix-spark-plug","title":"LFR6AIX-11 Iridium IX Spark Plug","description":"The iridium alloy, known for its extremely high melting point, makes these plugs ideal for today's advanced, high-output engines.\n\nConstruction features include trivalent metal plating for superior resistance to corrosion and seizing, corrugated ribs to prevent flashover, and a pure alumina silicate ceramic insulator that provides exceptional strength and efficient heat transfer. A copper core further aids in heat dissipation, while triple seals ensure a leak-free performance.\n\nKey specifications include a 14mm thread diameter with a 1.25mm thread pitch, a gasket seat type, a 26.5mm reach, and a 5\/8\" hex size. The fine wire iridium center electrode measures 0.6mm and is projected, paired with a standard nickel ground electrode featuring a taper cut shape. This spark plug has a heat range of 6 and is designed for longevity, with a manufacturer-estimated lifespan of 50,000 miles. Torque specifications are provided for both cast iron (18-25.3 lb. ft.) and aluminum (18-21.6 lb. ft.) cylinder heads.","brand":"NGK","offers":[{"title":"Default Title","offer_id":52663098704184,"sku":"NGK6619 - LFR6AIX-11","price":9.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687074291.jpg?v=1784323799","url":"https:\/\/store.motormia.co\/products\/lfr6aix-11-iridium-ix-spark-plug","provider":"MOTORMIA","version":"1.0","type":"link"}
