Frequently Asked Questions (FAQ)

Q: Will this ignition coil fit my Ford?

A: Please check the Vehicle Compatibility list above. This coil covers Ford F-150, F-250, F-350, Expedition, Mustang, Explorer, E-Series, Excursion, Thunderbird and Lincoln Navigator/Mark VIII with 4.6L, 5.4L, and 6.8L Modular engines (1996–2005). If you’re unsure, message us with your Year/Make/Model and we’ll confirm compatibility.

Q: What is the difference between all these OEM part numbers?

A: Ford updated the ignition coil design several times over the production run of the Modular engine. F7TZ12029AB was the original part number, with subsequent revisions (BA, CA, CC) incorporating minor design improvements. The listed numbers are commonly used as cross-references for this coil application. Verify the original OE number, connector, and mounting design before ordering.

Q: What do DG508 and FD503 mean?

A: DG508, FD503, and C1454 are aftermarket catalog cross-reference numbers. Brand ownership and catalog formatting may vary by supplier.

Q: Is this an OEM part or aftermarket?

A: This is a high-quality OEM-equivalent replacement part manufactured to meet or exceed original Ford factory specifications. The OEM part numbers listed are for reference and cross-compatibility purposes only.

Q: How do I know if my ignition coil is failing?

A: Common symptoms include engine misfires or rough idle, check engine light (CEL) with codes P0300–P0308, poor fuel economy, difficulty starting, and loss of power under acceleration. We recommend scanning for fault codes before replacing.

Q: How many ignition coils are included?

A: This listing includes eight identical ignition coils. Many compatible V8 engines use eight coils, one per cylinder. The 6.8L V10 normally uses ten coils, so this package does not provide a complete V10 replacement set. Confirm the required quantity before ordering.

Q: Is installation difficult?

A: Installation is straightforward and DIY-friendly. You typically need a 7mm or 8mm socket and extension bar. The process takes about 30–45 minutes for a V8. No special tools or programming required.
