How many spark plugs does a Dodge have?
Most Dodge vehicles use one spark plug per cylinder. That means the total number of spark plugs generally equals the engine’s cylinder count: four plugs for a four‑cylinder, six for a six‑cylinder, eight for a V8, and so on. There are rare exceptions in older or specialty engines, but this is the standard in Dodge’s modern lineup.
Overview: one spark plug per cylinder in most Dodge engines
In practical terms, the number of spark plugs corresponds to the number of cylinders in the engine. Common Dodge configurations include inline-4 with 4 plugs, V6 with 6 plugs, and V8 with 8 plugs. Some older or specialty engines may use two plugs per cylinder, but this design is uncommon in current production vehicles.
Common engine layouts and plug counts
Below is a quick reference for typical Dodge engines you’ll encounter in street cars and SUVs.
- Inline-4 or 4-cylinder engines: 4 spark plugs
- V6 engines (including the Pentastar family): 6 spark plugs
- V8 engines (such as the Hemi family in many Dodges): 8 spark plugs
- Dual-plug-per-cylinder variants (rare and usually older or specialty engines): 2 spark plugs per cylinder, totaling twice the cylinder count
Note: The exact count for a given vehicle can be influenced by engine revisions or specialty configurations. Always verify with the owner's manual or a dealer if you are unsure. For the most common modern Dodge models, counts align with the number of cylinders.
How to verify the exact spark plug count for your Dodge
Because Dodge engines vary by model and year, the definitive count is in your vehicle’s documentation or by inspecting the engine itself. Here is how you can confirm:
- Check the engine’s cylinder count and configuration for your specific model (e.g., inline-4, V6, V8).
- Look up the engine code in the owner’s manual or the official Mopar service manuals or parts catalog to find the exact spark plug specification.
- Physically inspect the engine: count the spark plugs or note if there is a single coil per plug or any dual-plug-per-cylinder arrangement (rare in modern Dodges).
In short, the best source for your exact number is the vehicle’s manual or a dealer/official catalog using your VIN. If in doubt, a qualified mechanic can confirm the spark plug count for your engine family.
Summary
Across Dodge’s modern lineup, the standard rule is one spark plug per cylinder. A four-cylinder has four plugs, a six-cylinder six plugs, and an eight-cylinder eight plugs. Rare exceptions exist in older or specialty engines, but for everyday Dodge vehicles, you’ll typically match the plug count to the cylinder count. Always verify with your specific model’s documentation or a dealer if precision is required.

How many spark plugs does a 2008 Dodge Ram 1500 have?
A 2008 Dodge Ram 1500 with the 5.7L HEMI V8 engine has 16 spark plugs, with two per cylinder. The other 4.7L V8 engine also uses 16 spark plugs.
- 16 spark plugs: The 2008 Dodge Ram 1500 is equipped with the 5.7L HEMI V8 engine (or the 4.7L V8) which uses two spark plugs per cylinder.
- Two per cylinder: This dual-plug system allows for more efficient combustion.
- Total: Since there are eight cylinders in the V8 engine, the total number of spark plugs is 8×2=168 cross 2 equals 168×2=16.
Why does Dodge have 16 spark plugs?
After a number of years, Chrysler engineers solved this by adding a second spark plug. Two ignition points mean a faster, more complete burn, better power and performance, fewer emissions, and a tiny bump in fuel efficiency. It wasn't about doubling horsepower — but about cleaning up the ignition.
