Over continuous heat cycles, the factory pencil coils suffer from internal dielectric breakdown and compromised epoxy insulation, leading to secondary winding arcing and intermittent cylinder misfires (DTC P0300–P0303). Compounded by factory spark plugs experiencing rapid ground electrode erosion under forced-induction cylinder pressures, the widened plug gaps place excessive electrical strain on the coil pack drivers inside the powertrain control module (PCM).\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive refresh kit provides direct coil-on-plug replacements paired with laser-welded iridium spark plugs designed specifically for turbocharged applications. The coils feature high-conductivity copper primary and secondary windings encased in high-dielectric epoxy potting to withstand heavy thermal loading without micro-arcing. Matching OEM dwell and discharge profiles, this assembly directly supersedes factory references \u003cstrong\u003eCM5Z12029C\u003c\/strong\u003e, \u003cstrong\u003eCM5Z12029B\u003c\/strong\u003e, and \u003cstrong\u003eUF736\u003c\/strong\u003e. The paired fine-wire iridium spark plugs feature a minimal surface area center electrode to significantly decrease firing voltage requirements, providing a concentrated, stable flame kernel that prevents quenching under peak boost.\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; margin-bottom: 20px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2014-2017 Ford Fiesta\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e1.0L EcoBoost Fox I3 \/ B299\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e123 hp \/ 125 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eCM5Z12029C, CM5Z12029B, UF736, KIN133734TOP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2014 Ford Fiesta SE 1.0L L3 Turbo EcoBoost\u003c\/li\u003e\n  \u003cli\u003e2015 Ford Fiesta SE 1.0L L3 Turbo EcoBoost\u003c\/li\u003e\n  \u003cli\u003e2016 Ford Fiesta SE 1.0L L3 Turbo EcoBoost\u003c\/li\u003e\n  \u003cli\u003e2017 Ford Fiesta SE 1.0L L3 Turbo EcoBoost\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the B299 Fiesta?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2014-2017 Ford Fiesta equipped with the 1.0L EcoBoost Fox engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre these spark plugs pre-gapped for turbocharged EcoBoost engines?\u003c\/strong\u003e\u003cbr\u003e Yes, they come pre-gapped to factory forced-induction specifications, though checking gap clearance prior to torque-down is recommended workshop practice.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Compact Engineering Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet the exact diagnostic parameters and electrical tolerances of Ford's European-designed EcoBoost powertrain, this direct replacement kit ensures zero check engine lights, immediate throttle response, and smooth idle delivery across daily commuting and spirited driving.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50594069610744,"sku":"DS-ETDS1WGSU","price":71.95,"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-ford-fiesta-2014-2017-1-0l-1.jpg?v=1790056687","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-ford-fiesta-2014-2017-1-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
