Over time, the factory coil-on-plug epoxy potting degrades, leading to internal thermal breakdown and dielectric puncture within the primary and secondary winding layers. This deterioration produces intermittent secondary voltage leaks, spark blow-out under high cylinder pressure, P0300-P0308 diagnostic trouble codes, unburned fuel wash, and accelerated catalytic converter deterioration.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive ignition service kit replaces tired factory hardware with upgraded high-dielectric coil assemblies and fine-wire iridium spark plugs. The coil packs feature high-purity oxygen-free copper (OFC) windings insulated with heat-resistant epoxy potting to prevent internal voltage tracking. Paired with laser-welded iridium spark plugs, the package delivers lower required firing voltage, superior thermal resistance, clean flame kernel propagation, and factory-matched blade terminals for plug-and-play installation.\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;\"\u003e2007-2009 Chrysler Aspen\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 \/ HG 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;\"\u003e235–303 hp \/ 300–330 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\u003e2007 Chrysler Aspen Limited 4.7L V8\u003c\/li\u003e\n  \u003cli\u003e2008 Chrysler Aspen Limited 4.7L V8\u003c\/li\u003e\n  \u003cli\u003e2009 Chrysler Aspen Limited 4.7L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Chrysler Heavy-Haul Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered for full-size SUV duty cycles, this ignition package ensures consistent spark energy under heavy trailering and sustained grade climbs, maintaining peak torque delivery without ignition drop-off.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50447737389304,"sku":"DS-EFC80W5M5","price":101.95,"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-chrysler-aspen-2007-2009-4-7l-1.jpg?v=1788622648","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-chrysler-aspen-2007-2009-4-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
