Chrysler Aspen Ignition Coil Guide: 2007-2009 Models
Diagnose and replace a faulty ignition coil on your 4.7L or 5.7L HEMI V8 to restore engine performance and prevent further damage.
- A flashing check engine light means stop driving to prevent costly catalytic converter damage.
- This is an easy DIY repair. The coils are on top of the engine, held by one bolt each.
- For best results, stick with reputable aftermarket brands like Delphi, NGK, or Standard Ignition (SMP).
- If your Aspen has over 100,000 miles, consider replacing all eight coils and the spark plugs at the same time.
Symptoms of a Bad Ignition Coil
When an ignition coil starts to fail on your Aspen, the signs are usually noticeable. Because each cylinder has its own coil, a single failure will cause a specific cylinder to stop firing correctly. 🎬 Learn more about how ignition coil problems affect your car. This is called a misfire.
- Rough Engine Idle: Your V8 will no longer sound or feel smooth at a stop. It may vibrate or shake noticeably.
- Loss of Power: With one or more cylinders not contributing, your Aspen will feel sluggish and weak, especially when accelerating.
- Check Engine Light: A steady Check Engine Light will almost always appear. A code reader will show codes like P0300 (random misfire) or P0301 through P0308, which point to a misfire in a specific cylinder (e.g., P0305 is cylinder 5).
- Worse Fuel Economy: The engine has to work harder to compensate for the dead cylinder, burning more fuel in the process.
- Trouble Starting: While less common if only one coil has failed, multiple weak coils can make it difficult to start the engine.
Choosing the Right Aftermarket Ignition Coil
You don't have to buy the expensive Mopar part from the dealer to get your Aspen running right. Many aftermarket brands offer excellent quality, often exceeding the original parts. However, not all aftermarket coils are created equal. They generally fall into three tiers.
| Brand Tier | Recommended Brands | Description |
|---|---|---|
| Premium Aftermarket / OEM Equivalent | Delphi, NGK, Hitachi, Standard Ignition (SMP) | These brands are often the original equipment manufacturers for many car companies. They offer top-tier reliability and performance that meets or exceeds factory specifications. For a daily-driven Aspen, these are your best bet for a long-lasting, trouble-free repair. |
| Quality Aftermarket | Spectra, Walker Products, Holstein | These brands provide a good balance of quality and value. They are a solid choice for owners looking for a reliable repair without the premium price tag. Performance is generally very close to OEM. |
| Economy / Performance | DriveWire, Global Parts, various "performance" brands | This category includes budget-friendly options and some "performance" coils that claim power gains. While tempting, be cautious. Forum discussions often suggest that for a stock engine, OEM or premium aftermarket coils provide the best reliability. Economy coils may have a shorter lifespan. |
