Comparison Insights: Making the Right Choice

When picking the best spark plugs for your Dodge Charger, you must first know your engine (V6 or V8) and then decide on your material priority (longevity vs. performance).

  • V6 (3.6L Pentastar) Owners: Your primary focus should be on longevity because replacing the plugs is a time-consuming job. Iridium plugs, like the Champion or the XP5701 set, are highly recommended for their 100,000+ mile lifespan. The ENA kit is an excellent choice if your coils are also showing wear.
  • V8 (5.7L/6.1L/6.4L HEMI) Owners: You have more material choices. The HEMI uses 16 spark plugs, making replacement more expensive but generally easier to access.
  • For Maximum Performance: If you frequently track your V8 or are heavily tuned, Champion Copper Plus plugs (Products 2 & 7) offer the absolute best conductivity and spark energy, but be prepared to swap them out every 15,000 to 30,000 miles.
  • For Balance and Longevity (V8): Iridium and Laser Iridium plugs (NGK and Champion Iridium) provide huge lifespan benefits (up to 100,000 miles) and are the best choice for reliable daily driving, reducing the frequency of replacing all 16 plugs.
  • For High-Output SRT Models: The 6.1L and 6.4L V8s benefit from the heat resistance of Platinum (Product 9) or the sheer durability of Laser Iridium.

Final Verdict: Our Top Recommendations

Choosing the best plug depends heavily on your driving style and engine. Here are our categorized picks:

The Longevity King (V8 HEMI): If you hate maintenance and want the absolute longest life for your 5.7L, go with the 16 pc NGK Laser Iridium Spark Plugs. Their dual-precious metal construction maintains gap stability far better than standard Iridium.

The Best Value Performance Option (V8 HEMI): For those who don’t mind changing plugs more often for maximum spark conductivity, the 16 pc Champion Copper Plus Spark Plugs are the clear winner. They offer OE reliability at a fantastic price point.

The V6 Daily Driver Champion: The 6 pc Champion Iridium Spark Plugs compatible with Dodge Charger 3.6L V6 delivers exactly what the Pentastar needs: superb reliability and maximum interval life, making that complicated installation worthwhile for years to come.

The Complete Ignition Fix: If you have a V6 and are chasing misfires, the ENA Set of 6 Ignition Coils & Iridium Spark Plugs offers an unbeatable package deal to refresh your entire ignition system at once.


Best Spark Plugs For Dodge Charger: Comprehensive FAQ

Q1: Does the Dodge Charger V8 really use 16 spark plugs?

Yes, the 5.7L, 6.1L, and 6.4L HEMI V8 engines found in the Dodge Charger use two spark plugs per cylinder, totaling 16 plugs. This design (known as dual ignition) is used to ensure a more complete and efficient combustion of the fuel mixture, which is particularly important for the HEMI’s unique hemispherical combustion chamber design.

Q2: What is the recommended service interval for Dodge Charger spark plugs?

The interval depends heavily on the material:

  • Copper Plugs: Typically recommended for replacement every 12,000 to 30,000 miles.
  • Iridium/Platinum Plugs: Standard recommendations range from 80,000 to 100,000 miles. Always check your specific owner’s manual for factory specifications, especially for late-model V6 and V8 engines.

Q3: Should I use copper, platinum, or iridium plugs in my HEMI V8?

  • Copper: Best for high-performance, short-interval maintenance due to its superior conductivity. Ideal for modified or heavily tracked engines.
  • Platinum: A good midpoint; handles heat better than copper and offers longer life than copper, suitable for moderate performance and extended intervals.
  • Iridium: Provides the best longevity and superior resistance to high heat and electrical erosion. This is the most practical choice for a daily-driven Dodge Charger V8 as it dramatically reduces maintenance frequency.

Q4: What are the symptoms of bad spark plugs in a Dodge Charger?

Failing Dodge Charger spark plugs typically lead to several noticeable issues, including a rough or unstable idle, reduced engine power and acceleration, lower fuel economy, difficulty starting the engine, and engine misfires (often resulting in the “Check Engine” light illuminating). Replacing old or fouled plugs usually resolves these performance issues.

Q5: Do I need to gap iridium spark plugs for my Dodge Charger?

While many Iridium plugs (like the Autowxjq set) come pre-gapped, it is strongly recommended to always verify the gap before installation using a wire-style gap tool. Even though they are durable, the gap can sometimes shift during shipping. The correct Dodge Charger spark plug gap setting is critical for efficient ignition.

Q6: If I have a V6 Charger with over 100k miles, should I replace the ignition coils too?

Yes, for high-mileage 3.6L V6 Chargers, replacing the ignition coils along with the Iridium spark plugs is wise preventative maintenance. Coils degrade over time and fail under high heat stress, which can lead to misfires even with new plugs. Kits like the ENA package are designed specifically for this comprehensive ignition refresh.
