The OEM coil boots tend to dry rot over time, causing parasitic micro-arcing against the cylinder head. This voltage leak triggers intermittent misfires, a rough idle, and poor fuel efficiency during towing or heavy load applications. Furthermore, standard factory spark plugs wear down their center electrodes quickly. This widens the spark gap, forcing the internal windings of the OEM ignition coils to overwork, eventually causing a complete thermal breakdown and flashing diagnostic trouble codes.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis upgraded ignition service kit pairs highly conductive copper-core ignition coils with advanced iridium spark plugs to permanently resolve D40 misfire issues. The upgraded coils utilize premium epoxy potting to resist high-frequency thermal shock, protecting the internal windings from voltage failure. Thick, high-temp silicone coil boots deliver maximum dielectric strength to effectively block secondary voltage leaks. By integrating iridium spark plugs, the system requires substantially less primary voltage to bridge the spark gap. Iridium's extreme melting point guarantees consistent electrode integrity over tens of thousands of miles, maximizing cylinder fuel burn efficiency, restoring throttle response, and stabilizing idle dynamics.\u003c\/p\u003e\n  \n  \u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2005-2019 Nissan Frontier\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eVQ40DE \/ D40\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e261 hp \/ 281 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e224338J11C, 224488J100, 224488J110, 224488J111, C1406-6, IC479\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2005-2019 Nissan Frontier (4.0L V6)\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Nissan Durability Standard\u003c\/h3\u003e\n  \u003cp\u003eEngineered to handle the rigorous payload demands of heavy towing and extensive off-road articulation, this heavy-duty ignition kit ensures your D40 Frontier maintains reliable, continuous pulling power without triggering misfire-related check engine lights.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48395518771448,"sku":"DS-E833D1PL2","price":189.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-nissan-frontier-2005-2019-4-0l-v6-1.jpg?v=1778783895","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-iridium-spark-plugs-for-nissan-frontier-2005-2019-4-0l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
