As the factory coils age, internal windings break down, leading to voltage leaks and weak spark delivery. Simultaneously, standard factory spark plugs experience accelerated electrode wear, widening the gap beyond specification. This results in sluggish throttle response, random cylinder misfires, unburnt fuel washing the cylinder walls, and a noticeable drop in towing capability. For the heavy WS chassis, these inefficiencies compound, severely degrading lower-RPM torque and overall drivability.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete ignition overhaul addresses Hemi-specific thermal degradation by utilizing upgraded epoxy resins and heavy-duty primary and secondary copper windings in the coils to ensure maximum dielectric strength and thermal shock resistance. Higher voltage output ensures a complete burn of the air-fuel mixture, crucial for the dual-spark-plug cylinder head design. Paired with 16 performance iridium spark plugs, the system delivers an ultra-fine center electrode that requires less firing voltage while providing a highly concentrated, stable spark. The iridium construction offers exceptional resistance to heat and electrical wear, preventing gap expansion over time. This synergy restores lost horsepower, stabilizes idle, improves fuel efficiency, and provides the consistent ignition needed for heavy payloads.\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;\"\u003eJeep Wagoneer, Grand Wagoneer (2022)\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;\"\u003e5.7L \u0026amp; 6.4L Hemi V8 \/ WS Chassis\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;\"\u003e392 - 471 hp \/ 404 - 455 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;\"\u003eUF504, 56029129AA, 68060346AA, 5C1569, GN10352\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2022 Jeep Wagoneer 5.7L V8\u003c\/li\u003e\n  \u003cli\u003e2022 Jeep Grand Wagoneer 6.4L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Jeep Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle the immense weight and towing demands of the modern WS platform, this ignition upgrade ensures your Hemi V8 maintains relentless pulling power, reliable cold starts, and uncompromised off-road or highway capability under extreme thermal conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48266590159096,"sku":"DS-EI8A467QX","price":179.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-jeep-wagoneer-grand-wagoneer-2022-5-7l-6-4l-v8-1.jpg?v=1776823346","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-iridium-spark-plugs-for-jeep-wagoneer-grand-wagoneer-2022-5-7l-6-4l-v8","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
