Ford Fusion Ignition Coil Guide for 2006-2015 Models
Everything you need to know about replacing the ignition coils on your first or second-generation Ford Fusion.
- For 2006-2008 V6 models, a bad coil can damage the engine computer (PCM); address misfires immediately.
- Replacing coils on 4-cylinder engines is a simple DIY job; V6 rear coils are much harder, requiring intake manifold removal.
- Always replace spark plugs with ignition coils to ensure longevity and proper function.
- Stick with top-tier aftermarket brands like NGK, Denso, or Delphi for OEM-level quality without the OEM price.
Understanding Ignition Coil Failure in Your Fusion
Ignition coils on the 2006-2015 Ford Fusion are a common replacement item. When a coil fails, the engine cylinder it's responsible for can no longer fire correctly. This leads to a variety of noticeable symptoms. You might experience a rough idle, shaking, and a loss of power when you accelerate. Your check engine light will almost certainly turn on, and you may notice worse gas mileage because the engine is running inefficiently.
Known Issues: TSB for V6 Models and PCM Failure
Important for 3.0L & 3.5L V6 Owners (2006-2008): Ford issued Technical Service Bulletin (TSB) 13-4-17 for some early V6 Fusions. 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 have a V6 from this era with a misfire, it's critical to address it immediately. The TSB recommends replacing all six coils, all six spark plugs, and the PCM if a coil has failed and shows signs of heat damage or cracking. Ignoring this can lead to repeated coil failures and a much more expensive repair down the road.
🎬 Watch: How a failing coil can destroy your PCMChoosing the Right Aftermarket Ignition Coil
When shopping for new ignition coils, you have a choice between OEM (Motorcraft) and a wide range of aftermarket brands. While OEM is always a safe bet, several aftermarket brands offer excellent quality, sometimes from the same factory that makes the OEM part.
Here’s a breakdown of brand quality tiers based on owner feedback and mechanic consensus:
- Top Tier (OEM Quality or Better): These brands are known for reliability and are often the original equipment manufacturer. They are a safe choice for long-term performance. Brands include Motorcraft, NGK, Denso, Delphi, and Bosch. Many owners report that Denso is the actual OE manufacturer for Motorcraft coils.
- Mid-Tier (Reliable Aftermarket): These brands offer a good balance of price and quality. They are a solid choice for most daily drivers. This tier includes brands like Standard Motor Products (SMP) and Hitachi.
- Economy Tier: These are the most budget-friendly options. While they can get your car running, their long-term durability can be a gamble. It's often recommended to avoid the cheapest options if you plan on keeping your car for a long time.
Pro Tip: When one ignition coil fails, it's a good idea to replace all of them at the same time, especially on higher-mileage vehicles. Coils are exposed to the same heat and wear, so if one has failed, the others may not be far behind. Also, always replace spark plugs when you replace coils to ensure the best performance and prevent new coils from being damaged by old plugs.
Ford Fusion Ignition Coil Cost
| Part Type | Cost Range (Single Coil) | Notes |
|---|---|---|
| New OEM (Motorcraft) | $50 - $90 | Highest quality and guaranteed fit. |
| New Aftermarket (Top Tier) | $30 - $60 | Brands like NGK, Denso, and Delphi offer OEM quality for less. |
| New Aftermarket (Economy) | $18 - $30 | Budget-friendly but may have shorter lifespan. |
| Shop Labor | $75 - $250 | Varies by engine. V6 models cost more due to the rear bank being under the intake manifold. |
Frequently Asked Questions
How do I know which ignition coil is bad?
When the check engine light comes on, a diagnostic trouble code (DTC) is stored in the car's computer. You can read this code with an OBD-II scanner. Misfire codes are in the P0300 range (e.g., P0301 for cylinder 1, P0304 for cylinder 4). Codes in the P035X range (e.g., P0351, P0352) point specifically to a fault in the ignition coil circuit for that cylinder.

For 4-cylinder engines (2.3L, 2.5L), the job is very easy. The coils are right on top of the engine and held in by a single 8mm bolt. 🎬 Watch: Step-by-step coil and plug replacement for 4-cylinder engines For V6 engines (3.0L, 3.5L), the front three coils are just as easy, but the rear three are located under the upper intake manifold. Replacing the rear coils requires removing the intake, which makes the job more difficult and time-consuming.
Should I replace all the coils at once?
Yes, it is highly recommended. All the coils on your engine have the same amount of wear. If one fails, the others are likely to fail soon. Replacing them all at once saves you from future breakdowns and repeated repair jobs. It's also best practice to replace the spark plugs at the same time.
Were there any recalls for the ignition coils?
No, there have been no specific recalls issued by the NHTSA for ignition coil failure on the 2006-2015 Ford Fusion. However, Ford did issue a Technical Service Bulletin (TSB) for 2006-2008 V6 models related to coil failure causing PCM damage.
