When increasing boost and cylinder pressure through ECU tuning, factory spark plugs can become a weak link. APR’s Iridium Pro plugs utilize Iridium—one of the strongest materials available—offering a melting point 152% higher than silver and 38% higher than platinum. This resilience allows the plugs to withstand the extreme thermal loads found in Stage 2+ and ethanol-fueled (E85) applications.\u003c\/p\u003e\n\u003cp\u003eFeaturing a \u003cstrong\u003eHeat Range 9\u003c\/strong\u003e (colder than stock), these plugs effectively dissipate heat to prevent pre-ignition and knock. The non-projected insulator design and copper core further enhance thermal management, while the optimized electrode requires lower voltage to produce a consistent, powerful spark. These are the ideal companion for high-boost setups and pair perfectly with \u003cstrong\u003eAPR Ignition Coils\u003c\/strong\u003e for a complete ignition system overhaul.\u003c\/p\u003e\n\u003ch4\u003eFeatures:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperior Durability:\u003c\/strong\u003e Iridium construction is significantly stronger than copper or platinum, resisting melting and cracking under high cylinder pressures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat Range 9:\u003c\/strong\u003e Optimized for tuned engines, running cooler than factory plugs to prevent power-robbing pre-ignition.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Performance Design:\u003c\/strong\u003e Non-projected insulator design specifically tailored for high-output and motorsport applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEthanol Ready:\u003c\/strong\u003e Optimized electrode design ensures reliable ignition even with hard-to-ignite fuels like E85.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEfficient Ignition:\u003c\/strong\u003e Requires lower supplied voltage to create a strong spark, reducing strain on the ignition coils.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Management:\u003c\/strong\u003e Integrated copper core dissipates heat rapidly to protect the electrode from thermal fatigue\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eReplacing the following part numbers.\u003c\/p\u003e\n\u003cp\u003eIf you would like to order in different quantities than 8 send a message.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e06K905601B\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e06K905601D\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e06K905601K\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e06K905601M\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e06Q905601E\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e06Q905601L\u003c\/span\u003e\u003c\/p\u003e","brand":"ECS Tuning","offers":[{"title":"Default Title","offer_id":47726796865710,"sku":"z1003100","price":245.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0527\/0549\/3166\/files\/IMG_2099.webp?v=1775996383","url":"https:\/\/gpoparts.com\/products\/apr-4-0t-ea824-spark-plugs-8","provider":"GPO Parts","version":"1.0","type":"link"}
