Our spark plugs are made from Iridium - one of the strongest materials available. They last longer than other materials with higher melting points, run cooler, resist preignition, and even require less voltage to produce a strong spark. The iridium electrode with its copper core is harder and stronger than other materials, can dissipate heat more easily, and is better protected from melting, cracking, and other limitations found with standard plugs.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e152% higher melting point than silver, 125% higher than copper, and 38% higher than platinum\u003c\/li\u003e\n\u003cli\u003eHeat range 9 spark plug (Similar: Bosch 3, Brisk 10, Champion 4, Denso 27,  and NGK 9)\u003c\/li\u003e\n\u003cli\u003eAcceptable for high performance \/ tuned and stock vehicle applications alike\u003c\/li\u003e\n\u003cli\u003eOptimized electrode design for hard to ignite fuels, such as ethanol\u003c\/li\u003e\n\u003cli\u003e1 step colder than OEM (Gen 1 B48, Gen 1\/2 B58, \u0026amp; S58)\u003c\/li\u003e\n\u003cli\u003eCooler operating temperature than stock plugs\u003c\/li\u003e\n\u003cli\u003eResists preignition better than stock plugs\u003c\/li\u003e\n\u003cli\u003eAn excellent match for Dinan ignition coils\u003c\/li\u003e\n\u003cli\u003eStronger than copper and platinum\u003c\/li\u003e\n\u003cli\u003eLower required supplied voltage\u003c\/li\u003e\n\u003cli\u003eInsulator Material: Ceramic\u003c\/li\u003e\n\u003cli\u003eProjected insulator design\u003c\/li\u003e\n\u003cli\u003eThread diameter: 12mm\u003c\/li\u003e\n\u003cli\u003eInstall Torque: 17 Nm\u003c\/li\u003e\n\u003cli\u003eThread reach: 26.5mm\u003c\/li\u003e\n\u003cli\u003eHexagon: 14mm Bi-Hex\u003c\/li\u003e\n\u003cli\u003eSupplied Gap: 0.5mm\u003c\/li\u003e\n\u003cli\u003eTerminal Type: Cup\u003c\/li\u003e\n\u003cli\u003eSeat Type: Flat\u003c\/li\u003e\n\u003cli\u003eMade in the EU\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":50084181672188,"sku":"DNND640-0001","price":21.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1128\/7276\/files\/f75a6712b67eee5a6838155384830d9dL.jpg?v=1784135509","url":"https:\/\/jdcustomsusa.com\/ja\/products\/dinan-b48-b58-s58-iridium-spark-plug-heat-range-9-12mm-x-26-5mm-x-14mm-flat-single","provider":"JD Customs U.S.A","version":"1.0","type":"link"}
