For the 2008 Dodge Charger, the firing order depends on which engine is installed. The most common order you’ll see quoted is for the 5.7-liter Hemi V8, while the V6 options use different sequences. The exact order can vary by engine code, so it’s important to verify your specific powertrain.
In this article, we break down the firing orders by engine type and offer guidance on where to find the precise sequence for your particular Charger. Understanding the firing order helps when diagnosing misfires, replacing spark plugs, or performing ignition-related maintenance.
Engine options in the 2008 Charger
The 2008 Charger lineup included multiple engine choices. The primary ones were a 5.7-liter Hemi V8 used in the RT (and related models) and several V6 options (such as 3.5L and 3.7L variants). Each engine family uses its own firing order, so the correct sequence depends on which engine your car has.
5.7L Hemi V8 (RT)
The 5.7L Hemi V8 is the most common engine associated with the Charger’s high-performance variant. This engine uses eight ignition coils (coil-on-plug) and follows a specific firing order that is widely documented for Hemi V8s.
- 1
- 8
- 4
- 3
- 6
- 5
- 7
- 2
That firing order—1-8-4-3-6-5-7-2—is standard for many 5.7L Hemi engines and is what you’ll typically find referenced for the 2008 Charger’s Hemi-equipped versions. If you’re servicing a Hemi, follow this sequence for spark-plug-related work and ignition diagnostics.
V6 engines (3.5L/3.7L)
The 3.5L and 3.7L V6 engines used in the 2008 Charger have different firing orders from the Hemi. The exact sequence can vary by engine family and production year. To ensure accuracy, consult the factory service manual or the engine block diagram specific to your vehicle’s engine code (these codes are typically stamped on the engine and referenced in manuals). If you don’t have the manual handy, you can also check a dealership or qualified auto-repair database for the precise firing order for your exact engine variant.
How to verify the correct firing order on your own
When in doubt, use these steps to confirm the correct firing order for your 2008 Charger:
- Identify the exact engine type by checking the build sheet, VIN decoding, or the engine code stamped on the engine block.
- Consult the official service manual or a trusted repair database for the precise firing order corresponding to that engine code.
- Look for an engine diagram on the valve cover or cylinder head area where cylinder numbering and coil/plug positions are shown.
- If performing maintenance, ensure spark plugs are torqued to specification and that ignition components are reconnected in the correct sequence to avoid misfires.
Using the correct firing order is essential for proper engine operation. An incorrect sequence can lead to misfires, rough running, or potential damage to ignition components.
Summary
The 2008 Dodge Charger’s firing order depends on the engine installed. The 5.7L Hemi V8 commonly uses the order 1-8-4-3-6-5-7-2. The V6 options (3.5L and 3.7L) have their own distinct sequences, which vary by engine code. Always verify the exact firing order for your vehicle’s engine by consulting the factory service manual, engine code stamping, or a reliable repair database to ensure accuracy for maintenance and diagnostics.
