Ignition Coil

The Motorcraft DG-520 is a precision-engineered ignition coil designed to restore smooth idle and consistent performance in naturally aspirated Ford and Lincoln 3.5L and 3.7L V6 platforms. By utilizing a factory-spec 12-volt design, this coil ensures perfect communication with the vehicle's PCM, effectively eliminating misfires and preventing the "ghost" codes often triggered by generic aftermarket alternatives. Each unit is built with high-dielectric silicone boots that resist tearing and internal windings optimized for high-voltage stability. Technical construction focuses on long-term reliability, featuring a patented spring/resistor design that provides superior RFI suppression. This prevents electronic interference with vehicle systems, a common issue with lower-quality coils. This component is rigorously tested to meet or exceed 100,000-mile durability standards. Compatibility is specific to naturally aspirated engines, including the Ford Edge (2007–2018), Explorer (2011–2019), F-150 (2011–2017), Mustang (2011–2017), Taurus/Flex (2008–2019), and various Lincoln models (2007–2018). Please note that this product is NOT compatible with 3.5L EcoBoost (turbocharged) models. Always verify your specific engine configuration before installation. For maintenance, if your vehicle requires servicing of the rear cylinder bank, it is highly recommended to replace all coils simultaneously while the intake manifold is removed to minimize labor costs. This component is intended for use with matching ignition system hardware and is sold as an individual coil unit.
