ENA Ignition Coil Pack for Ford Lincoln 3.5L EcoBoost Turbo — UF646 Set of 1, 3-Pin Bolt-On 12V Replacement

ENA UF646 is a direct-fit ignition coil pack engineered for turbocharged 3.5L Ford and Lincoln EcoBoost V6 engines, offered here as a single replacement unit.

This coil pack is designed to replace OEM references such as BL3Z12029C, DG549 and UF646 on select Ford and Lincoln turbocharged 3.5L V6 applications from 2011 through 2020. It uses a three-terminal, bolt-on mounting layout and a 12V electrical design intended to restore consistent spark delivery for vehicles equipped with EcoBoost turbochargers. Before ordering, verify your vehicle uses the 3-pin turbo/EcoBoost connector because 2-pin or naturally aspirated engines are not compatible.
