✓【 DIRECT FIT FOR MULTIPLE VEHICLE MODELS 】 This Ignition Coil Pack fits your 2.0L/2.5L L4 – for Ford (Transit Connect 2014-2021 2.5L, Fusion 2010-2020 2.0L/2.5L, C-Max 2013-2018 2.0L, Escape 2009-2019 2.5L), for Lincoln MKZ (2013-2020 2.0L, 2011-2012 2.5L), and for Mercury (Mariner 2009-2011 2.5L, Milan 2010-2011 2.5L). Replace all 4 coils and plugs at once to stop misfires, rough idle, hesitation, check-engine lights – restore lost power and throttle response.
✓【 OEM-PERFECT FIT WITH A TWIST 】 Precision-molded to meet OEM specs – no modifications, no splicing wires. Coils directly replace UF621, 9E5Z12029A, 9E5Z12029C, L50718100, L50718100A, UF-621, UF621T, and more. Spark plugs directly replace 5019, LTR5GP. Pull them out of the box and install immediately.
✓【 BUILT FOR UNDER-HOOD HELL 】 We didn't just copy the OEM; we upgraded the guts. Coils are wound with German-imported enameled copper wire and potted in Japanese epoxy resin to withstand extreme vibration. Silicone boots resist the brutal 105°C (peak 125°C) heat that cooks cheaper coils. Say goodbye to cracked boots leaving you stranded on the highway – these are tested from -40°C to survive Alaskan winters and Arizona summers.
✓【 WHY IRIDIUM? 】 The ultra-fine iridium electrode fires a concentrated, powerful Spark Plug even under heavy load. The isostatic ceramic insulator prevents carbon tracking and flashover, ensuring consistent combustion for 60,000+ miles. Expect fewer fuel-wasting misfires, smoother idle, and noticeably quieter engine at highway speeds.
