Is Your Camaro's Ignition Coil Failing?
When an ignition coil on your 5th Generation Camaro starts to go bad, the symptoms are usually obvious. Because each cylinder relies on its own coil, a single failure can make your engine run poorly. The most common sign is a Check Engine Light, often paired with a noticeable change in engine performance.

If your Check Engine Light is flashing, it indicates a severe engine misfire. Unburnt fuel can get into the exhaust system, which can quickly overheat and damage your expensive catalytic converters. If you see a flashing light, you should stop driving as soon as it is safe to do so.
Choosing the Right Aftermarket Ignition Coil
When it's time to replace a coil, you have many options. The quality can vary significantly between brands, so it's important to choose wisely.
Tier 1: OEM & Premium Aftermarket
For owners who want the best reliability and performance, sticking with the original equipment manufacturer (OEM) or equivalent is the safest bet. ACDelco is the OEM parts brand for GM. Delphi is also a major OEM supplier, and their parts are often identical to ACDelco parts, sometimes at a lower price. Brands like NGK and Bosch are also highly reputable and produce OEM-quality coils.
Tier 2: Performance Aftermarket
Brands like Granatelli, Edelbrock, and Mishimoto market their coils as performance upgrades, often claiming higher voltage output. For a stock or lightly modified Camaro, most owners report that these coils offer no noticeable performance gains over standard OEM-quality coils. They may be beneficial for highly modified engines running forced induction or E85 fuel, but for most daily drivers, the extra cost is not justified.
Tier 3: Economy & Value Brands
Many brands like DriveWire, True Tech, and others offer coils at a much lower price point. While tempting, these parts can be a gamble. Forum discussions show that some owners have had success with budget-friendly brands, but others have experienced premature failures. If you choose an economy brand, be aware that the quality and longevity may not match that of more established manufacturers.
Pro Tip: Diagnosing and Replacing Coils
If you have a misfire, you can easily identify the bad coil using an OBD-II scanner. A code like P0305 points to a misfire in cylinder 5. To confirm, you can 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 found your problem.

Frequently Asked Questions
Should I replace all ignition coils at once?
It's a good practice, especially if your Camaro has over 100,000 miles. Ignition coils are exposed to the same heat and wear, so if one fails, others may not be far behind. Replacing them all at once with the spark plugs can save you from future breakdowns.
What's the difference between V6 and V8 ignition coils?
The V6 (LLT/LFX) and V8 (LS3/L99) engines use different ignition coils. They are not interchangeable. Furthermore, some V8 engines used a square-style coil (like the LS3) while others used a round style. Always verify the correct part number for your specific engine before ordering.
Were there any recalls for 2009-2014 Camaro ignition coils?
No, there were no specific recalls for ignition coils on the 2009-2014 Camaro. There was a well-known recall for the ignition *switch* where a driver's knee could bump the key and turn the car off, but this is unrelated to the ignition coils themselves.
Can a bad ignition coil cause other problems?
Yes. Driving for an extended period with a misfiring coil can cause unburnt fuel to enter the exhaust, potentially damaging the catalytic converter, which is a very expensive repair. It also puts extra strain on the remaining cylinders.
