Expect roughly $8-$60 for a four-plug set on the 2013 Avenger’s four-cylinder option, or $12-$150 for a six-plug set on the six-cylinder option, depending on plug type and brand. Labor is extra if you’re not doing the replacement yourself.
Engine options and plug counts
The number of spark plugs you need depends on the engine. The 2013 Dodge Avenger offered a 2.4-liter four-cylinder and a 3.6-liter V6; the plug count aligns with the engine size.
To determine the exact count for your vehicle, confirm your engine variant: four plugs for the 2.4L I4, six plugs for the 3.6L V6.
- 2.4L Tigershark I4 engines use 4 spark plugs.
- 3.6L Pentastar V6 engines use 6 spark plugs.
Knowing the plug count helps you estimate parts cost, service time and whether you can DIY or need a shop appointment.

Prices vary by metal, brand and retailer. The ranges below reflect common options you’ll find at chain auto parts stores and online marketplaces in the United States as of 2024–2026. Always verify current pricing and compatibility.

Where to buy and installation tips
Shopping tips and practical considerations can affect the final price and fit. Here are common points to consider before buying and replacing.
