Over time, original epoxy potting degrades, leading to internal micro-arcing, dielectric insulation breakdown, and erratic secondary voltage output. Paired with aged spark plugs suffering from widened electrode gaps, this breakdown manifests as intermittent hesitation, rough idle, reduced towing torque, and persistent P0300-P0308 misfire codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive kit includes 8 direct-fit ignition coils and 8 matching iridium spark plugs engineered to withstand severe underhood environments. The coil packs feature high-grade internal electrolytic copper windings for maximum magnetic saturation and rapid primary-to-secondary voltage transformation. Encased in high-dielectric thermoplastic housings with corrosion-resistant blade terminals, these coils resist voltage leakage. The fine-wire iridium spark plugs offer superior thermal resilience and minimal spark degradation, ensuring consistent flame kernel propagation and reliable combustion under heavy payload demands.\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;\"\u003e2006-2008 Jeep Commander\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;\"\u003e4.7L PowerTech V8 \/ XK Platform\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;\"\u003e235 - 305 hp \/ 305 - 334 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;\"\u003eUF270, 56028138AB, 56028138AD, 56028138AE, 56028138AF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2006 Jeep Commander (XK) 4.7L V8 (Base, 65th Anniversary Edition)\u003c\/li\u003e\n  \u003cli\u003e2007 Jeep Commander (XK) 4.7L V8 (Sport, Limited)\u003c\/li\u003e\n  \u003cli\u003e2008 Jeep Commander (XK) 4.7L V8 (Sport, Limited)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Jeep Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle the sustained loads of heavy trail use, payload hauling, and steep grade towing, this direct-fit ignition kit delivers reliable arc stability without risk of spark blowout or electronic interference.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50447723921656,"sku":"DS-ENHOBL57K","price":104.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-and-iridium-spark-plugs-for-jeep-commander-2006-2008-4-7l-1.jpg?v=1788622074","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-jeep-commander-2006-2008-4-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
