Ford Fusion Ignition Coil Guide (2006-2020): Symptoms, Costs, and Replacement
Diagnose and fix your Ford Fusion's misfire by choosing the right aftermarket ignition coil.
- A flashing check engine light means pull over immediately to prevent expensive catalytic converter damage.
- For 2006-2008 V6 models, a bad coil can destroy the engine computer (PCM); address misfires urgently.
- On V6 engines, replacing the three rear coils is a difficult job that requires removing the intake manifold.
- To save money without sacrificing quality, choose an OEM-equivalent brand like Denso or NGK.
Is Your Fusion Running Rough? It Could Be an Ignition Coil
A failing ignition coil is a common problem on the Ford Fusion that can cause poor engine performance. When a coil goes bad, the spark plug for that cylinder can't get the high voltage it needs to fire correctly. This results in an engine misfire, which you might feel as a shudder, hesitation, or jerking, especially when idling or accelerating. Ignoring a bad coil can lead to more serious issues, including expensive damage to your catalytic converter.
TSB for 2006-2008 V6 Models: A Critical Warning
Ford issued Technical Service Bulletin (TSB) 13-4-17 for some 2006-2008 Fusion models with 3.0L or 3.5L V6 engines. This TSB notes that a failing ignition coil can short out and damage the Powertrain Control Module (PCM), which is the main engine computer. If you own one of these models and experience a misfire (codes P0351-P0356), it is critical to stop driving and address the issue immediately. 🎬 Watch this deep dive on how bad coils kill the PCM. The recommended repair includes replacing all six coils, all six spark plugs, and potentially the PCM itself to prevent repeated failures.
Choosing the Right Aftermarket Ignition Coil
When replacing a coil, you don't have to buy the expensive OEM part from a dealer. Quality aftermarket brands can offer the same performance for less money. However, not all aftermarket coils are created equal. For ignition parts, it's wise to stick with reputable brands to avoid premature failure.
- OEM-Equivalent Brands (Best Value): Brands like Denso, NGK, and Hella are excellent choices. Denso is often the original equipment manufacturer for Ford, meaning the part is identical to the Motorcraft one, just in a different box. Beck Arnley is another option that often sources parts from OEM suppliers. These brands provide OEM quality without the high dealer price tag.
- Performance Brands: Brands like Accel and Granatelli are designed for high-performance applications. They often claim to provide more energy than stock coils. While they are a quality option, they may be unnecessary for a daily-driven Fusion that has not been modified.
- Standard/Value Brands: Brands like Prenco and Karlyn STI are more budget-friendly. While they can save you money upfront, some owner experiences suggest that economy-grade ignition parts may not have the same longevity as OEM-equivalent options.
Pro Tip: V6 Engine Replacement
On four-cylinder Fusion engines, all ignition coils are easily accessible on top of the engine. However, on the V6 engines, the front three coils are easy to reach, but the rear three are located under the intake manifold. Replacing the rear coils is a more involved job that requires removing the manifold, which significantly increases labor time and cost.
Cost to Replace Ford Fusion Ignition Coils
The cost can vary based on your engine and whether you do the work yourself. Replacing coils on a 4-cylinder is a simple DIY job. A V6 will cost more in labor if you take it to a shop due to the difficulty of accessing the rear coils.
| Item | Estimated Cost |
|---|---|
| New Aftermarket Ignition Coil (Single) | $22.00 – $317.36 |
| New OEM (Motorcraft) Ignition Coil (Single) | $55 - $115 |
| Shop Labor (Per Coil, 4-Cylinder) | $29 - $43 |
| Shop Labor (All Coils, V6) | $200 - $400+ (due to intake manifold removal) |
Frequently Asked Questions (FAQ)
Do I need to replace all ignition coils at once?
While you can replace just the one that failed, ignition coils are wear-and-tear items. If your Fusion has over 100,000 miles, the other coils may fail soon. Replacing them all at once, along with the spark plugs, can save you from future breakdowns and repeated repair jobs.
Can a bad ignition coil damage other parts?
Yes. A continuously misfiring cylinder can allow unburned fuel to enter the exhaust system, which can overheat and destroy your catalytic converter—a very expensive repair. On 2006-2008 V6 models, a bad coil can also short out and damage the engine computer (PCM).
Were there any recalls for Ford Fusion ignition coils?
No, there have been no specific recalls from the NHTSA for ignition coil failure on the 2006-2020 Ford Fusion. 🎬 See a step-by-step coil replacement for 2006-2012 models. However, a TSB was issued for 2006-2008 V6 models for coils damaging the PCM. There was a recall for 2014-2015 Fusions related to the ignition switch, which is a different part.
How do I know which ignition coil is bad?
A check engine light code will tell you which cylinder is misfiring (e.g., P0301 for cylinder 1, P0302 for cylinder 2). A simple way to confirm the coil is the problem is to swap the suspected bad coil with a coil from a known good cylinder. If the misfire code moves to the new cylinder, you've confirmed the coil is faulty.

Technical Specifications
OEM Part Numbers: DG514 DG522 DG549 DG562 UF553 UF621 UF670 UF674
This is a direct-fit, coil-on-plug (COP) style ignition coil. The replacement procedure for 4-cylinder engines requires only an 8mm socket and ratchet. For V6 engines, accessing the rear bank of coils requires removal of the upper intake manifold. The hold-down bolt torque specification is approximately 62 in-lbs (about 5 ft-lbs).
