Over time, the internal primary and secondary copper windings develop micro-fractures, while the dielectric epoxy breaks down, causing secondary voltage leakage. Paired with aged standard plugs exhibiting excessive gap erosion, this degradation leads to unburned hydrocarbon build-up, erratic cold starts, sluggish throttle response, and catastrophic catalyst-damaging P0300-series misfire codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis ignition kit integrates reinforced coil-on-plug assemblies engineered with high-conductivity oxygen-free copper windings and direct-fit blade terminal connectors to resist heat soak and voltage drop. The paired iridium spark plugs feature laser-welded, ultra-fine center electrodes that require lower strike voltages while resisting thermal shock and spark erosion. The result is rapid flame-front propagation, consistent high-RPM energy transfer, and a dependable factory idle.\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;\"\u003e2007-2012 Dodge Caliber\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;\"\u003e2.0L (ECN) \/ 2.4L (ED3) World Engine \/ PM 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;\"\u003e158-174 hp \/ 141-165 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;\"\u003eUF557, 4606824AB, 4606824AC, IC637, C1587, E1057, 5C1644\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2007-2012 Dodge Caliber SE (2.0L L4)\u003c\/li\u003e\n  \u003cli\u003e2007-2012 Dodge Caliber SXT (2.0L L4)\u003c\/li\u003e\n  \u003cli\u003e2007-2012 Dodge Caliber R\/T (2.4L L4)\u003c\/li\u003e\n  \u003cli\u003e2011-2012 Dodge Caliber Mainstreet \/ Express \/ Heat \/ Rush \/ Uptown (2.0L \u0026amp; 2.4L L4)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Dodge Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to withstand daily commuter punishment and prolonged thermal loads, this ignition package ensures zero check-engine lights, rapid cold-start cranking, and consistent power delivery across the entire rev band.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50448284975352,"sku":"DS-E7YUN2EMP","price":99.95,"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-dodge-caliber-2007-2012-2-0l-2-4l-1.jpg?v=1788638339","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-dodge-caliber-2007-2012-2-0l-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
