{"product_id":"iridium-long-life-spark-plug-8","title":"Iridium Long Life Spark Plug","description":"The Denso SK20HR11 Iridium Long Life Spark Plug is engineered for extended durability and optimal performance, often serving as a factory-installed component on luxury vehicles from manufacturers like GM, Toyota, Honda, and Mitsubishi. This spark plug utilizes a 0.7mm iridium-tipped, laser-welded fine wire center electrode, paired with a platinum-tipped ground electrode, to ensure efficient ignition and longevity.\n\nThe plug is 100% pre-fired to guarantee the highest quality. A purified alumina powder insulator provides exceptional strength and thermal conductivity, while the five-rib insulator design prevents flashover. A copper-glass seal ensures a gas-tight bond between the center electrode and the insulator.\n\nKey specifications include a 14mm thread diameter with a 1.25mm pitch, a 26.5mm reach, and a 5\/8\" (16mm) hex size. The center electrode is projected, and the spark plug is designed with a resistor. The Longevity is estimated between 80,000 to 100,000 miles. Torque specifications vary depending on the cylinder head material: 26-30 lb. ft. for cast iron and 15-22 lb. ft. for aluminum.","brand":"DENSO","offers":[{"title":"Default Title","offer_id":52687675687224,"sku":"SK20HR11","price":103.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663679691.jpg?v=1784886000","url":"https:\/\/store.motormia.co\/products\/iridium-long-life-spark-plug-8","provider":"MOTORMIA","version":"1.0","type":"link"}
