This insulation failure leads to secondary winding voltage leaks, weak arc transfer, and spark scatter under load. Concurrently, standard worn spark plugs suffer from increased gap erosion, significantly raising the primary coil electrical load and causing hesitation, sluggish acceleration, unburnt hydrocarbon build-up, and rough cold starts.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis service kit pairs high-output coil-on-plug assemblies with fine-wire iridium spark plugs for synchronized combustion efficiency. The coils are manufactured with high-grade copper windings and vacuum-sealed thermal epoxy potting to insulate against high-voltage leakage and internal arcing. Matched with erosion-resistant iridium center electrodes, this package provides consistent spark energy, precise arc targeting, reduced electrical demand on the ignition driver, and dependable combustion stability under high operating temperatures.\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;\"\u003e2003-2010 Ford Fiesta\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;\"\u003e1.6L Duratec (Sigma) \/ B-Platform (B256)\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;\"\u003e100 hp \/ 107 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;\"\u003eFD505, FD-505, UF621, UF-621\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2003-2010 Ford Fiesta 1.6L 4-Cylinder (All Trim Levels)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Ford Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet stringent European hot-hatch tolerances, these direct-fit components guarantee factory pin alignment, seamless ECU integration, and complete resolution of OBD-II misfire fault codes without requiring harness modifications.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50452009451768,"sku":"DS-EBFMER6E6","price":74.95,"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-2003-2010-1-6l-1.jpg?v=1788716782","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-ford-fiesta-2003-2010-1-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
