Over time, OEM pencil coils succumb to dielectric breakdown, high-voltage arcing, and micro-cracking across the silicone boot. Coupled with electrode erosion on high-mileage factory plugs, widened plug gaps increase the required firing voltage, straining primary driver circuits in the PCM and causing hesitation, rough idle, and typical P0300 through P0303 misfire DTCs under peak boost.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis service kit provides a complete refresh engineered to withstand the rigorous cylinder pressures of direct-injected forced induction. The three coil-on-plug pencil units feature high-grade magnetic copper windings, vacuum-potted epoxy insulation to eliminate internal voids, and high-temp silicone boots that resist thermal hardening and spark flashover. Matched with fine-wire iridium spark plugs, the system delivers lower required breakdown voltage, superior quenching resistance, and consistent spark kernel propagation across the entire powerband.\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;\"\u003e2015-2018 Ford Focus\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;\"\u003e\n\u003cstrong\u003e1.0L EcoBoost I3\u003c\/strong\u003e \/ \u003cstrong\u003eC346\u003c\/strong\u003e\n\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;\"\u003e\n\u003cstrong\u003eCM5Z12029C\u003c\/strong\u003e, \u003cstrong\u003eUF736\u003c\/strong\u003e, \u003cstrong\u003eCM5Z12029B\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2015 Ford Focus S \/ SE 1.0L EcoBoost (C346)\u003c\/li\u003e\n  \u003cli\u003e2016 Ford Focus SE 1.0L EcoBoost (C346)\u003c\/li\u003e\n  \u003cli\u003e2017 Ford Focus SE 1.0L EcoBoost (C346)\u003c\/li\u003e\n  \u003cli\u003e2018 Ford Focus SE 1.0L EcoBoost (C346)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the C346 Focus?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2015-2018 Ford Focus equipped with the \u003cstrong\u003e1.0L EcoBoost\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre the spark plugs pre-gapped for the 1.0L turbo application?\u003c\/strong\u003e\u003cbr\u003e Yes, but checking electrode gap against factory specification (0.028-0.031 in) prior to installation is recommended to guarantee zero spark blowout under boost.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Commuter Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for exacting European-platform tolerances, these direct-replacement ignition components preserve factory emissions compliance, smooth power delivery, and CEL-free reliability throughout daily operational duty cycles.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50594072756472,"sku":"DS-EDDS7U40M","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-focus-2015-2018-1-0l-1.jpg?v=1790056720","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-ford-focus-2015-2018-1-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
