{"product_id":"iridium-spark-plug-105","title":"Iridium Spark Plug","description":"The APR Iridium Pro Spark Plugs are an excellent upgrade for tuned engines, offering superior performance and durability. Constructed with iridium, these spark plugs boast a melting point 152% higher than silver, 125% higher than copper, and 38% higher than platinum, along with greater material strength than copper and platinum. The design intent is for high performance and tuned vehicle applications, featuring a projected insulator and requiring lower voltage for ignition.\n\nThese plugs operate at a cooler temperature than stock and are optimized with a special electrode design for fuels that are difficult to ignite, such as ethanol. They also provide better preignition resistance compared to stock plugs, making them ideal for high boost, high cylinder pressure, high cylinder temperatures, and high power situations. The plugs have a 19mm thread reach, 14mm thread diameter, 16mm hexagon size, and a gasket seat type. The recommended installation torque is 25 Nm, and they are manufactured in the EU.\n\nThe heat range is rated at 9, which is comparable to Bosch 3, Brisk 10, Denso 27, and NGK 9. They are suitable for a wide range of Audi, Porsche, and Volkswagen models, specifically those with 2.0T and 3.0T engines. Always use the vehicle selector to confirm exact fitment for your specific application.","brand":"APR","offers":[{"title":"Default Title","offer_id":52686955544888,"sku":"Z1003101","price":9.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687887412.webp?v=1784878882","url":"https:\/\/store.motormia.co\/products\/iridium-spark-plug-105","provider":"MOTORMIA","version":"1.0","type":"link"}
