{"product_id":"ruthenium-hx-spark-plug-set","title":"Ruthenium HX Spark Plug Set","description":"The NGK Ruthenium HX spark plug set is a performance-focused 8-piece ignition upgrade engineered for 1999-2013 Chevrolet Silverado 1500 trucks equipped with 4.8L, 5.3L, 6.0L, and 6.2L V8 engines. By utilizing patented ruthenium technology, these plugs are specifically developed to meet the demands of modern engines, offering superior durability against wear and high-temperature performance over traditional iridium or platinum designs.\n\nEach plug is manufactured in an ISO 11565-certified facility and undergoes rigorous testing for thermal shock, mechanical vibration, and combustion efficiency. The plugs feature a 5\/8-inch wrench size. Please note that while these are pre-gapped for general use at 0.040 inches, you will need to adjust the gap to meet the specific requirements of your engine application to ensure optimal performance.\n\nInstallation requires verifying the specific gap setting for your engine trim and year. As this kit is specialized for specific Chevrolet Silverado V8 configurations, ensure your vehicle engine code matches the compatible list.","brand":"NGK","offers":[{"title":"Default Title","offer_id":52663097622840,"sku":"2024118094","price":97.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687076944.jpg?v=1784323783","url":"https:\/\/store.motormia.co\/products\/ruthenium-hx-spark-plug-set","provider":"MOTORMIA","version":"1.0","type":"link"}
