In short, the number of spark plugs depends on the engine. A 2013 Avenger with the 2.4-liter inline-4 uses four spark plugs, while the 3.6-liter V6 uses six.
During that model year, Dodge offered two engines for the Avenger. The choice determines not only performance but the spark plug count and replacement needs. This article clarifies which engines use how many plugs and how to identify yours.
Engine options and spark plug counts
One spark plug per cylinder is standard, so the total matches the engine's cylinder count. Here are the two official options for the 2013 Avenger and their plug counts.
- 2.4-liter inline-4 (Tigershark): 4 spark plugs
- 3.6-liter Pentastar V6: 6 spark plugs
Knowing your engine helps with maintenance decisions, such as scheduling spark plug replacement and selecting the correct parts.
How to verify which engine your car has
Check the badge on the back or side of your vehicle, the VIN, or the engine cover under the hood. If you are unsure, consult the owner's manual or a dealer service department, as the plug count will align with the engine designation in your VIN.
Summary
The 2013 Dodge Avenger can have either four spark plugs (2.4L I4) or six spark plugs (3.6L V6). Confirm your engine to determine the exact plug count and maintenance needs.
