Helpful Comparison Insights

Choosing the right spark plugs for Dodge Challenger requires recognizing the core differences between the engine types and materials.

When dealing with the 5.7L Hemi V8, remember that these engines use two spark plugs per cylinder, meaning you always need a pack of 16. In contrast, the 3.6L V6 Pentastar engine only requires 6 plugs.

Iridium vs. Copper: If you own a daily driver 5.7L Challenger, iridium options like the NGK Iridium IX or the Champion Iridium are superior for longevity. You won’t have to swap out those 16 plugs as often (iridium often lasts 3x longer). However, for maximum electrical conductivity and the strongest possible spark, especially if you tune the engine aggressively, the Champion Copper Plus plugs are still the preferred performance choice, even if they require more frequent replacement.

V6 Ignition Kits Offer Best Value: For 3.6L V6 owners, kits like the Set of 6 Ignition Coil Packs & Iridium Spark Plugs or the ENA Set of 6 Ignition Coils & Iridium Spark Plugs provide outstanding value. Since the V6 is known to be slightly more complex to service than the V8, changing the coil packs simultaneously with the plugs is smart preventative maintenance that maximizes uptime.

Final Verdict

Making the best selection for your Challenger depends on your engine size and driving habits:

The Hemi (5.7L) Longevity Champion: Go with the 16 pc NGK Iridium IX Spark Plugs. NGK is an industry leader, and this set offers the perfect balance of performance enhancement and long life, meaning less time spent changing those 16 plugs.

The V8 Performance Enthusiast Pick: If you chase every horsepower and don’t mind getting your hands dirty every 30,000 miles, the 16 pc Champion Copper Plus Spark Plugs deliver the highest conductivity and strongest raw spark.

The V6 (3.6L) All-in-One Solution: The best overall value and reliability for the V6 is the Set of 6 Ignition Coil Packs & Iridium Spark Plugs (XP5701 replacement). Replacing the coils and plugs together guarantees a completely refreshed ignition system designed for long-term daily use.

Comprehensive FAQ on the Best Spark Plugs For Dodge Challenger.

How often should I change the spark plugs in my Dodge Challenger?

The replacement interval depends significantly on the plug material and your engine. For 5.7L Hemi V8s, standard copper or nickel plugs (like the NGK Standard) should typically be replaced every 30,000 to 32,000 miles. Premium iridium spark plugs (for both 5.7L and 3.6L V6 engines) can often last between 60,000 to 100,000 miles. Always check your owner’s manual for the factory-recommended service schedule.

Do I need 16 spark plugs for my Challenger?

If you own a Challenger with the 5.7L Hemi V8, the answer is yes. The Hemi engine uses a dual spark plug design, meaning there are two spark plugs for Dodge Challenger per cylinder, totaling 16 plugs for the engine. If you have the 3.6L Pentastar V6, you only need 6 spark plugs.

Is it necessary to replace the ignition coils when changing spark plugs?

For V8 engines, it’s not always necessary, but for V6 models (3.6L), it is highly recommended, especially after 80,000 miles. Ignition coils and spark plugs age together, and replacing them simultaneously (as offered in the coil and plug kits) prevents future misfires and is a cost-effective way to ensure a complete ignition system refresh.

What is the difference between Iridium and Copper spark plugs for my Hemi?

Copper plugs offer the best electrical conductivity, providing a stronger spark, which is why performance tuners often prefer them. However, copper wears quickly. Iridium plugs have lower conductivity than copper but are significantly harder and more resistant to heat and wear, providing much longer life (up to 100k miles) and consistent performance for daily driving.

Should I get pre-gapped plugs, or should I gap them myself?

While many premium spark plugs for Dodge Challenger are listed as “pre-gapped,” it’s always best practice to check the gap with a proper gapping tool before installation. Shipping vibrations can sometimes alter the gap, and ensuring the measurement matches your engine’s specification (which varies by year and model) is crucial for optimal engine performance and longevity.

Can I use the same spark plugs in my 5.7L Challenger as my 3.6L Challenger?

Absolutely not. The physical size, thread pitch, and heat range specifications are entirely different between the V6 and V8 engines. Always confirm the compatibility using the reference numbers or Amazon Garage tool to ensure you select the correct set for your specific Challenger engine.
