Dodge Avenger Ignition Coil Guide: Symptoms, Brands, and Replacement (2007-2014)
Experiencing engine misfires or a rough idle in your Avenger? A failing ignition coil is a likely culprit.
- A flashing check engine light signals a severe misfire that requires immediate attention to prevent catalytic converter damage.
- Replacing all coils and spark plugs at once is the best practice for high-mileage Avengers to ensure reliability.
- This is a simple DIY repair that can be done with basic tools in under an hour, saving significant labor costs.
- Stick with reputable aftermarket brands like NGK, Denso, Delphi, or Bosch for a reliable, long-lasting repair.
Is Your Avenger's Ignition Coil Failing?
A bad ignition coil isn't something you can ignore for long. When a coil starts to fail, it can't deliver the strong, consistent spark your engine needs to run properly. This leads to noticeable performance problems that can get worse over time. If you experience any of the symptoms below, it's time to inspect your ignition coils.
Choosing the Right Aftermarket Ignition Coil
When replacing an ignition coil, you don't have to buy the expensive Mopar part from the dealership. Many aftermarket brands offer excellent quality, often for a fraction of the price. However, not all aftermarket parts are created equal. It's best to avoid the cheapest, no-name options, as they can fail prematurely.
Brand Quality Tiers for Dodge Avenger
- Top-Tier Aftermarket (OEM-Equivalent): Brands like NGK, Denso, Delphi, and Bosch are often the original equipment manufacturers for many car brands. They provide reliability and performance that is equal to or sometimes better than the stock Mopar part. These are a trusted choice for a long-lasting repair.
- Quality Mid-Range Aftermarket: Brands such as Standard Motor Products (SMP) and Hitachi have a strong reputation for producing reliable ignition components that offer a great balance of price and quality.
- Economy/Budget-Friendly: Brands like DriveWire or other private labels offer the lowest price point. While tempting, their long-term durability can be a gamble. They might be a temporary fix, but for peace of mind, investing in a mid-tier or top-tier brand is often the smarter financial decision in the long run.
A Note on TSB 9003081
For 2012-2013 Avengers, Chrysler issued a Technical Service Bulletin (TSB) stating that certain types of dielectric grease are not compatible with the silicone material of the spark plug boots and can cause them to deteriorate. When replacing your coils, ensure you use a silicone-safe dielectric grease on the new boots or follow the manufacturer's instructions.
Ignition Coil Replacement Costs for Dodge Avenger
The cost to replace an ignition coil can vary based on your engine and whether you do it yourself or go to a shop. The job is very DIY-friendly, especially on the 4-cylinder engine.
| Cost Category | Estimated Price Range |
|---|---|
| Single Aftermarket Coil | $28 - $100 |
| Single OEM Mopar Coil | $85 - $130 |
| Shop Labor (Single Coil) | $43 - $63 |
| Total Shop Replacement (1 Coil) | $144 - $164+ |
Pro Tip: Replace in Sets
Ignition coils are wear-and-tear items. If one has failed, the others are likely not far behind, especially on a higher-mileage vehicle. To save on future labor costs and ensure consistent performance, it's highly recommended to replace all ignition coils at the same time, along with the spark plugs.
Frequently Asked Questions
Should I replace all ignition coils at once?
Yes, it's a good idea. All the coils on your engine have endured the same conditions and mileage. If one fails, others may soon follow. Replacing them all at once, along with new spark plugs, restores ignition performance and prevents you from having to do the same job again in a few months.
How do I know which ignition coil is bad?
When a coil fails, the check engine light will come on. A mechanic or an OBD-II scanner can read the diagnostic trouble code (DTC). A code like P0301 indicates a misfire in cylinder 1, while a code like P0351 points directly to a fault in the ignition coil circuit for cylinder 1. You can then swap the suspected bad coil with a known good one from another cylinder. If the misfire code follows the coil to the new cylinder, you've confirmed the coil is the problem.

No, this is a very beginner-friendly job, especially on the 2.4L 4-cylinder engine. The coils are located directly on top of the engine and are held in by a single bolt. You only need basic hand tools like a ratchet, an extension, and a Torx bit (usually a T30). 🎬 See this walkthrough for replacing your 2.4L coils and plugs. The V6 engines are also straightforward, though the rear coils can be slightly harder to reach.
🎬 Watch how to access the rear coils on V6 engines.Are there any recalls for the Dodge Avenger ignition coil?
No, there are no specific recalls for ignition coil failure on the 2007-2014 Dodge Avenger. There was a recall for some 2007-2008 models related to a wiring connector that could cause stalling, but it was not directly for the ignition coils themselves.
