Thermal cycling introduces micro-fractures in the coil housing, causing high-voltage dielectric breakdown, intermittent spark blow-out, and unburned hydrocarbon accumulation. Simultaneously, factory standard spark plug gaps widen from electrode erosion, forcing tired primary windings to work harder and triggering low-RPM misfires, rough idle harmonics, and sluggish throttle response under heavy payload demands.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis ignition kit integrates four direct-fit coil-on-plug assemblies engineered with high-density internal copper windings and reinforced thermoplastic housings to resist thermal fatigue. Paired with ultra-fine wire iridium spark plugs, the system lowers required firing voltage while providing a concentrated, stable arc kernel. Precision blade terminals and OEM-spec pin fitment ensure zero resistance variance across the cylinder head, stabilizing idle combustion and maximizing fuel burn efficiency.\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;\"\u003e2013-2020 Ford Ranger\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;\"\u003e2.5L Duratec I4 \/ T6 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;\"\u003e164 hp \/ 167 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\u003e2013-2020 Ford Ranger 2.5L 4-Cylinder (Gasoline)\u003c\/li\u003e\n  \u003cli\u003eIncludes all XL, XLS, and XLT trims equipped with the 2.5L I4 Duratec engine\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Ford Utility Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to withstand demanding duty cycles and prolonged payload hauling, this ignition service kit restores factory combustion integrity to ensure reliable cold starts and consistent torque delivery without spark-breakdown under load.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50452008665336,"sku":"DS-E2VK0M2RY","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-ranger-2013-2020-2-5l-1.jpg?v=1788716662","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-ford-ranger-2013-2020-2-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
