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.\nB48\/B58\/S58\nAlways check sizes, gap, and heat range specs before installing. Installation of the wrong length plug can cause damage to the engine. You must verify this before installing the plug.\n\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\n\u003cp\u003eUpgrade your vehicle's ignition system with the Dinan B48\/B58\/S58 Iridium Spark Plug, designed to deliver superior performance and durability for both tuned and stock engines. Made from iridium, a highly durable material with a melting point 152% higher than silver and 38% higher than platinum, these plugs are engineered to withstand extreme conditions. The iridium electrode, featuring a copper core, provides a harder, stronger tip that dissipates heat efficiently and resists melting, cracking, and preignition, making it ideal for high-performance applications. The plug's heat range 9 and its one step colder temperature than OEM ensure optimal operation under demanding conditions, including high boost and aggressive tuning. Its design supports better ignitability for fuels like ethanol and reduces the voltage needed for a strong spark, resulting in improved fuel efficiency and engine responsiveness. Compatibility with Dinan ignition coils ensures a seamless upgrade for enthusiasts seeking enhanced ignition performance. The spark plug features a ceramic insulator with a projected insulator design, a 12mm thread diameter, and a 26.5mm thread reach, all crafted with precision to fit specified BMW models. Proper installation torque of 17 Nm and a supplied gap of 0.5mm promote reliable operation and longevity. This EU-made spark plug not only boosts engine performance but also contributes to cleaner emissions, with Prop 65 compliance ensuring safety. Whether used in high-performance tuning or stock setups, the Dinan Iridium Spark Plug offers a significant upgrade to engine ignition components, promoting smoother starts, improved throttle response, and extended service life.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eMade from iridium for enhanced durability and high melting point\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeat range 9 for optimal performance across various driving conditions\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOne step colder than OEM to prevent preignition and overheating\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOptimized electrode design for difficult fuels like ethanol\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatible with Dinan ignition coils for seamless integration\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCeramic insulator with a projected design for reliable spark delivery\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eThread diameter of 12mm and thread reach of 26.5mm for precise fit\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSupplied with a 0.5mm gap and installation torque of 17 Nm\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eManufactured in the EU with Prop 65 compliance for safety\u003c\/li\u003e\u003c\/ul\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":53855160926524,"sku":"dnnD640-0001","price":48.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1865\/9007\/files\/f75a6712b67eee5a6838155384830d9dL.jpg?v=1784843633","url":"https:\/\/necycleshop.com\/products\/dinan-b48-b58-s58-iridium-spark-plug-heat-range-9-12mm-x-26-5mm-x-14mm-flat-single","provider":"NE Cycle Shop","version":"1.0","type":"link"}
