Spark plugs for a 2015 Dodge Charger typically cost between $2 and $20 per plug, depending on the material and brand. A six-cylinder 3.6L V6 requires six plugs, while most V8 configurations require eight plugs. Expect a full replacement set to range roughly from $12 to $160 before labor.
Engine options and required spark plugs
Different engines in the 2015 Charger lineup use different numbers of spark plugs. Use this guide to estimate how many plugs you’ll need for your specific model:
- 3.6L Pentastar V6 — requires 6 spark plugs
- 5.7L Hemi V8 — requires 8 spark plugs
- 6.4L Hemi (392) — requires 8 spark plugs
- 6.2L Supercharged Hemi (Hellcat) — requires 8 spark plugs
Knowing the exact engine helps you budget for replacement and confirms the total parts count before you buy.
Average spark plug prices by material
Prices vary by the spark plug’s material and brand. Here are typical price ranges you’ll see at major retailers for a single plug:
- Copper core plugs: about $2 to $5 each
- Platinum plugs: about $4 to $10 each
- Iridium plugs: about $8 to $20 each
When you multiply by the number of plugs in your engine, this can lead to a wide range for a full set, depending on the chosen material.
Estimated total cost for a full set
To estimate the total price before labor, multiply the per-plug price by the number of plugs, then add potential discounts or taxes. For reference:
- 6-plug set (3.6L V6): copper $12–$30, platinum $24–$60, iridium $48–$120
- 8-plug set (V8 variants): copper $16–$40, platinum $32–$80, iridium $64–$160
Labor costs vary by shop and location, but an experienced auto technician often charges about 0.5–1.5 hours for a plug replacement on a modern V6 or V8, depending on access and whether ignition coils must be removed. DIY replacement saves labor if you’re comfortable with basic tools.
Note: Always verify the exact engine in your Charger (3.6L, 5.7L, 6.4L, or Hellcat) to determine the precise number of plugs and the recommended plug type for your vehicle.
How to choose the right plug type and plan your purchase
Choosing between copper, platinum, or iridium depends on your priorities: lower upfront cost, longer life, or optimal performance. Here are quick guidelines to help you decide:
- Budget-conscious replacement: copper plugs offer the lowest upfront cost.
- Balanced performance and longevity: platinum plugs are a common middle ground.
- Maximum durability and longer intervals between changes: iridium plugs are the premium option.
Consider your driving habits, maintenance schedule, and whether you prefer a DIY replacement or professional service when budgeting for parts and labor.
Summary
For a 2015 Dodge Charger, the spark plug count depends on the engine: 6 for the 3.6L V6, and 8 for the 5.7L, 6.4L, and Hellcat versions. Spark plug prices range from about $2 to $20 per plug based on material, with total sets typically spanning $12–$160 before labor. Labor will add to the total, but doing it yourself can save money. Always confirm your exact engine and choose a plug type that matches your maintenance goals and driving style.
