Is Your Durango Running Rough? It Could Be The Coil Boots.
If your 2011-2016 Dodge Durango is experiencing a rough idle, poor acceleration, or the check engine light is on, failing ignition coil boots are a likely culprit. These rubber boots are a common wear item that can crack and degrade from constant exposure to engine heat. Oil leaks from the valve cover gaskets, a frequent issue, can also saturate the boots, causing them to swell and fail prematurely. When a boot fails, voltage can escape, leading to a weak or non-existent spark. This causes an engine misfire, which triggers error codes like P0300, P0301, P0302, etc., 🎬 See how to diagnose and fix a specific cylinder misfire. and can lead to more severe engine problems if ignored.
Don't Ignore a Flashing Check Engine Light
A steady check engine light means a fault has been detected. However, a flashing check engine light signals a severe misfire. This is dumping unburnt fuel into the exhaust system, which can quickly destroy your expensive catalytic converters. If you see a flashing light, you should stop driving the vehicle as soon as it is safe to do so.
Choosing the Right Aftermarket Coil Boot Kit
When it's time for a replacement, you don't necessarily need to buy the expensive OEM Mopar parts. High-quality aftermarket brands offer reliable performance at a better price point. For a part like a coil boot, which is essentially a high-grade rubber insulator and spring, top aftermarket options are a smart choice.
- Denso: Denso is a well-respected OEM supplier for many automakers. Choosing their aftermarket coil boot kits means you are getting a part that meets or exceeds original factory quality. They are known for excellent fit and durability.
- Standard Motor Products (SMP): Standard is a trusted name in the aftermarket, offering parts that are designed to be direct OE replacements. Their boots are a solid, reliable option that provides good value.
Pro Tip: It is highly recommended to replace all coil boots at the same time, especially if your Durango has over 100,000 miles. They have all been exposed to the same conditions, so if one has failed, others are likely not far behind. This saves you from doing the same repair multiple times.

Frequently Asked Questions
Can I replace just the boots and not the entire ignition coil?
Yes. In many cases, the coil itself is still functional, and only the rubber boot has failed. Replacing just the boot and spring kit is a cost-effective way to solve the problem. However, if a boot is soaked in oil, inspect the coil for damage before reusing it.
Should I replace spark plugs at the same time?
It is best practice to replace the spark plugs when you replace the coil boots, especially if they are near their service interval (typically 100,000 miles). Worn spark plugs put extra strain on the ignition system. Since you'll already have everything apart, doing both at once saves on future labor costs.
Is this a difficult DIY job?
For the 5.7L Hemi V8, the job is relatively easy for a DIYer. For the 3.6L Pentastar V6, the front three coils (passenger side) are easy, but the rear three (driver's side) are located under the upper intake manifold. This requires more work and is considered an intermediate-level job.
Are there any recalls for Durango ignition coil boots?
No, there are no specific recalls from Dodge or NHTSA for ignition coil or boot failure on the 2011-2016 Durango. While recalls exist for other model years and different components, this specific issue is considered a maintenance or wear-and-tear item.
