Description
Bosch 0221504704 is an OE-quality coil-on-plug ignition coil for Ford modular V8 and V10 gasoline engines (4.6L, 5.4L, 6.8L) across 1997-2014 Ford, Lincoln, and Mercury cars, trucks, vans, and SUVs. The coil is a direct replacement for the Motorcraft DG508 and the 3W7Z-12029-AA OEM service number, with the Bosch winding and insulation system designed to deliver consistent secondary voltage, longer spark duration, and reduced misfire under load.
Signs You Need a New Ignition Coil

- Rough idle, hesitation, or surging during acceleration
- Reduced fuel economy and/or emissions failures
- Hard start or no-start on one or more cylinders
- Visible arcing, cracks, or carbon tracking on the coil boot
