Over time, high heat degrades the dielectric insulation, causing micro-arcing, secondary voltage leakages, and ignition misfires (DTC P0300-P0304). Paired with standard eroded spark plug gap clearances, this ignition degradation disrupts the electro-hydraulic MultiAir valvetrain's precise combustion sequence, resulting in sluggish throttle response and poor fuel economy.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement ignition service kit features four high-output ignition coils and four fine-wire iridium spark plugs. The coils are engineered with high-conductivity electrolytic copper windings, vacuum-infused dielectric epoxy, and heat-stabilized PBT thermoplastic housings to resist electrical bleed and insulation breakdown under sustained thermal stress. The matching iridium spark plugs feature a laser-welded fine-tip center electrode that reduces ignition voltage demand, minimizes flame kernel quenching, and ensures instantaneous flame propagation across all engine speeds.\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;\"\u003e2014-2016 Dodge Dart (2.4L L4)\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;\"\u003e2.4L Tigershark MultiAir II \/ PF 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;\"\u003e184 hp \/ 174 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;\"\u003eUF751, UF754, 5149168AI, 5149168AH, 68242286AA, 68242286AB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2014 Dodge Dart (GT, Limited, SXT) - 2.4L L4 Gas\u003c\/li\u003e\n  \u003cli\u003e2015 Dodge Dart (GT, Limited, SXT) - 2.4L L4 Gas\u003c\/li\u003e\n  \u003cli\u003e2016 Dodge Dart (GT, Limited, SXT) - 2.4L L4 Gas\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Dodge Caliber Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to restore factory transient throttle response, stable cold-start ignition, and smooth power delivery throughout the entire RPM band without triggering false misfire diagnostic trouble codes.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50430320115960,"sku":"DS-EN1RH7X7C","price":89.95,"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-dart-2014-2016-2-4l-1.jpg?v=1788455420","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-dodge-dart-2014-2016-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
