Ignition Coil Guide for 2015-2024 Chevrolet Camaro
Everything a Camaro owner needs to know about diagnosing, choosing, and replacing a failing ignition coil.
- A flashing check engine light means a severe misfire; pull over immediately to prevent catalytic converter damage.
- For most owners, premium aftermarket brands like NGK, Delphi, and Bosch offer the best balance of quality and value.
- Always replace spark plugs at the same time as ignition coils to ensure the longevity of the new parts.
- On V8 models, the stock ACDelco coils are very reliable; performance coils are often unnecessary for stock or lightly modified cars.
Is Your Camaro's Ignition Coil Failing?
When an ignition coil starts to go bad on a 6th Generation Camaro, the symptoms are usually obvious. Because each cylinder has its own coil, a single failure directly impacts how the engine runs. Ignoring these signs can lead to more expensive problems down the road, like a damaged catalytic converter.
Common Symptoms of a Bad Ignition Coil:
- Engine Misfires: This is the most common symptom. You'll feel a stumble, hesitation, or rhythmic shaking from the engine, especially at idle or during acceleration.
- Check Engine Light: A failing coil will almost always trigger the check engine light. Common codes include P0300 🎬 Watch this guide on diagnosing random misfire codes in Camaros. (random/multiple cylinder misfire) and P0301-P0308, where the last digit indicates the misfiring cylinder. If the light is flashing, it signals a severe misfire. You should pull over and stop driving as soon as it's safe to prevent damage.
- Reduced Power and Sluggishness: With one cylinder not firing correctly, your Camaro will feel noticeably less powerful and slow to accelerate.
- Rough Idle: The engine may vibrate or shake more than usual when you're stopped at a light.
- Worse Fuel Economy: Your gas mileage will drop because the engine has to work harder to compensate for the dead cylinder.
- Difficulty Starting: While less common if only one coil has failed, multiple weak coils can make the engine hard to start.
Known Issues, Recalls, and TSBs
While ignition coils are a normal wear item, it's good to be aware of any specific issues for your Camaro.
- Recalls: There are no active NHTSA safety recalls specifically for ignition coils on the 2015-2024 Camaro. There were recalls for the 2010-2015 models related to the ignition key and switch design, where a driver's knee could bump the key and turn the car off, but this is unrelated to the ignition coils themselves.
- Technical Service Bulletins (TSBs): General Motors issued TSB 21-NA-036 for misfire conditions on some 2016-2022 Camaros, which often points to a failing ignition coil as a potential cause.
- Engine-Specific Notes: The factory ACDelco coils on the V8 models (LT1, LT4) are generally considered very reliable. Some owners of V6 (LGX) models have noted coil failure as a primary suspect for misfires. For the 2.0L Turbo (LTG) engine, issues with the PCV system can sometimes lead to oil fouling the spark plugs, which puts extra strain on the coils and can cause premature failure.
Choosing the Right Aftermarket Ignition Coil
You don't have to buy an expensive OEM coil from the dealership. Many aftermarket brands offer excellent quality, often at a better price. Here’s how they generally stack up for your Camaro.
Brand Tiers for Chevrolet Camaro
| Tier | Brands | Notes |
|---|---|---|
| OEM / Premium Aftermarket | ACDelco, NGK, Delphi, Bosch | ACDelco is the original equipment manufacturer for GM. You can't go wrong with their parts for a direct, factory-quality replacement. Delphi was the original supplier to GM for many parts and is often identical to ACDelco, sometimes at a lower price. NGK and Bosch are highly respected ignition specialists. Many owners trust NGK for its quality and durability, sometimes even preferring it over OEM. |
| Performance Aftermarket | Granatelli, FAST, Mishimoto, Pertronix | These brands offer high-output coils that promise increased spark energy for better performance. They often claim benefits like quicker starts and improved throttle response. For a stock or lightly modified Camaro, the performance difference may not be noticeable, and the factory V8 coils are already very robust. These are best for heavily modified engines. |
| Standard Aftermarket | Standard Ignition, Hitachi, Denso, Walker Products, Holstein | These are solid, reliable brands that produce parts meeting or exceeding OEM specifications. They are a dependable choice for a daily driver and offer a good balance of quality and price. One Reddit user experienced multiple failures with a store brand (Duralast) and planned to switch back to OEM, highlighting the potential variability in this tier. |
| Economy Brands | DriveWire, True Tech, Global Parts, Skyward, URO Parts | These brands offer the lowest price point. While they can be a budget-friendly solution to get your car back on the road, their long-term durability and performance may not match the higher-tiered brands. Quality can be inconsistent. |
Pro Tip: It's highly recommended to replace all spark plugs when you replace your ignition coils. Worn spark plugs create more resistance, which can strain the new coils and cause them to fail prematurely. Also, if one coil has failed and your car has over 80,000 miles, it's wise to replace all of them at the same time, as the others are likely near the end of their service life.
Frequently Asked Questions (FAQ)
Do I need to replace all ignition coils at once?
If your Camaro has high mileage (over 80,000 miles) and one coil fails, it's a good idea to replace them all. The others have experienced the same amount of wear and may fail soon. If the car has lower mileage, you can get away with replacing only the faulty one.
Is an expensive performance coil worth it for my stock Camaro?
For a stock engine, probably not. The factory ACDelco coils, especially on the V8 models, are very efficient and reliable. Performance coils from brands like Granatelli or FAST are designed for modified engines and you likely won't feel a difference on a stock car.
What's the difference between ACDelco and Delphi coils?
Delphi was originally the parts manufacturing division of GM. For many components, a Delphi part is identical to the ACDelco part it was originally supplied for. You can often get the same quality at a lower price by choosing Delphi.
How difficult is it to replace the ignition coils on my Camaro?
It's a very easy job on all Camaro engines (2.0L, 3.6L, and 6.2L). The coils are located directly on top of the engine and are held in by a single bolt. The job requires basic hand tools and can typically be done in under an hour 🎬 See how easy it is to replace your coils and plugs., even for a beginner.
