Best Dodge Charger Spark Plugs: 9 Top Picks

You rely on your Dodge Charger for responsive acceleration, smooth idling, and reliable starts. Spark plugs are small parts, but they directly affect combustion quality, cold starts, throttle response, and misfire control.

In this guide, you will find carefully chosen spark plug options for several Charger engines, including 3.6L V6, 5.7L HEMI V8, 6.1L and 6.4L V8, and older 2.7L V6 applications. The right plug depends on your exact year, engine, required gap, thread size, and whether your HEMI uses 16 plugs, so always confirm fitment before ordering.

Before You Buy: Fitment Checklist

How We Picked These Spark Plugs

You want plugs that match your exact Charger engine, fit safely, and solve common drivability issues without creating new ones. We prioritized Charger-specific fitment, engine-year coverage, plug count, core and tip material, stated gap, brand reputation, clear buyer use case, and whether the listing gave enough detail to make a confident purchase.

Iridium and platinum plugs are usually best when you want longer service life and stable spark quality. Copper plugs can still make sense on older HEMI engines when you want a familiar replacement and are comfortable checking gap during installation.

NGK Iridium IX 6-Pack

If you own a 2011-2020 Dodge Charger with the 3.6L V6, this NGK Iridium IX 6-pack is the cleanest starting point. It gives you a full set for the V6, iridium tips for better wear resistance, and a Charger-specific fitment claim that keeps the buying decision simple.

Choose this set if your goal is a straightforward maintenance refresh for rough idle, aging plugs, soft starts, or mild throttle hesitation. Avoid it if you have a 5.7L, 6.1L, or 6.4L V8 because those engines use different plug counts and fitment requirements.

Why You’ll Like It

• Full 6-pack for a complete 3.6L V6 service
• Iridium tip helps maintain spark quality over time
• Good fit for daily drivers that need smoother starts and steadier idle
• Simple choice when you want an OE-style replacement path

Check Before Buying

Confirm your exact model year, engine, plug gap, and torque spec before installation. If your Charger still misfires after new plugs, inspect coils and boots next.

NGK Laser Iridium 16-Pack

If you are servicing a 5.7L HEMI Charger, the plug count matters. This NGK Laser Iridium set includes 16 plugs, which suits dual-plug 5.7L applications where replacing only half the set would leave uneven wear behind.

This is the strongest fit if you want a longer-life iridium option for daily driving, highway use, and occasional spirited runs. The main buyer hesitation is cost compared with copper, but the benefit is a more durable electrode material and a full matching set.

Why You’ll Like It

• Full 16-pack for compatible 5.7L HEMI Chargers
• Laser iridium design for long service life and stable spark
• Good choice when you want a complete refresh instead of mixed old and new plugs
• Useful for rough idle, weak starts, and aging plug replacement

Check Before Buying

Confirm your Charger uses the 5.7L V8 and verify the plug gap against your service information before installing all 16 plugs.

Champion Iridium 6-Pack

This Champion Iridium 6-pack is another strong option for 2011-2020 Charger 3.6L V6 owners. It is useful when you want a full V6 service set from a familiar ignition brand and you prefer a plug that is advertised around the 0.043 inch range.

Choose it for a practical daily-driver tune-up. Avoid it for HEMI engines or any Charger where your manual calls for a different thread, reach, or gap.

Why You’ll Like It

• Full 6-pack for compatible 3.6L V6 Chargers
• Iridium construction for better wear resistance than basic copper
• Good option for smoother idle and more consistent starts
• Clearer fitment than broad universal plug listings

Check Before Buying

Measure the gap before installation and adjust only if the plug design and manufacturer guidance allow it. Fine-wire iridium tips can be damaged by rough gapping tools.

NGK Iridium IX 16-Pack

This NGK Iridium IX 16-pack is a practical match for 5.7L V8 Charger owners who want an iridium set but do not need to overthink the service. Since the 5.7L setup can require 16 plugs, buying a full set helps keep all cylinders on the same maintenance schedule.

It is best for owners who want reliable everyday performance, steadier idle quality, and a more durable spark plug material than basic copper. It is not the right buy for V6 models or 6.1L/6.4L V8 applications unless your fitment check specifically says so.

Why You’ll Like It

• Full 16-pack for compatible 5.7L HEMI applications
• Iridium tips help resist electrode wear
• Good for complete tune-ups on high-mileage Chargers
• Helps avoid mixed plug age across cylinders

Check Before Buying

Do not assume every V8 Charger uses the same plug. Match the engine, year, and plug code before ordering.

Champion Copper Plus Spark Plugs 16-Pack

If you want a familiar copper replacement for a 2009-2019 Charger 5.7L V8, this Champion Copper Plus 16-pack is the practical budget pick. It gives you enough plugs for the full HEMI service and keeps the setup simple.

Choose this if you prefer a traditional copper-core plug and plan to check the gap before installation. Avoid it if you want the longest possible service interval, since iridium and platinum plugs usually hold their electrode shape longer.

Why You’ll Like It

• Full 16-pack for compatible 5.7L HEMI Chargers
• Copper core design for a familiar replacement feel
• Good option for older or high-mileage daily drivers
• Lower-cost path compared with many iridium sets

Check Before Buying

Shipping can sometimes shift plug gaps. Measure each plug and match the required gap for your exact Charger before installation.

Champion Copper Plus 16-Pack

This Champion Copper Plus set is aimed at earlier 2006-2008 5.7L V8 Chargers. It is a better match for those older HEMI applications than trying to force a later-year 5.7L plug set into the wrong model range.

It makes sense for a high-mileage Charger that needs a no-nonsense ignition refresh. The main limitation is service life compared with precious-metal plugs, so it is best for owners who do not mind routine maintenance.

Why You’ll Like It

• Specific 2006-2008 5.7L V8 fitment claim
• Full 16-pack for a complete dual-plug service
• Copper core can suit older HEMI maintenance routines
• Simple choice for restoring stable idle and clean starts

Check Before Buying

Early and later 5.7L HEMI plug requirements can differ. Confirm your year range, plug code, and gap before ordering.

Champion Platinum 16-Pack

If your Charger has a 6.1L or 6.4L V8, this Champion Platinum 16-pack belongs on your shortlist. It is more relevant for high-output V8 models than a 3.6L V6 or 5.7L-specific set.

Choose it when you want a full 16-plug service with platinum electrode wear resistance. The key caution is gap variation by year, so do not install based on the listing headline alone.

Why You’ll Like It

• Targets 6.1L and 6.4L Charger V8 applications
• Full 16-pack for dual-plug service
• Platinum electrode design offers better wear resistance than basic plugs
• Good fit for owners refreshing high-output V8 ignition systems

Check Before Buying

Confirm whether your model year calls for a 0.050 inch or 0.043 inch style gap before installation.

A-NAFTULY Iridium 6-Pack

The A-NAFTULY XP5701 6-pack is a broader aftermarket option for 3.6L applications. The visible listing includes Dodge Charger fitment, but it also covers several related Dodge, Chrysler, Jeep, and Ram models, so you should treat fitment verification as essential.

This is best for buyers who want an iridium-style 3.6L alternative and are comfortable checking part numbers carefully. Avoid it if you prefer a narrower Charger-only listing or if your service data calls for a different thread or gap.

Why You’ll Like It

• 6-pack format covers a complete V6 service
• Iridium tip with platinum core listing details
• Useful alternative when the exact fitment matches your Charger
• Includes warranty language on the listing

Check Before Buying

Verify the XP5701 reference, 12 mm thread detail, 0.040 inch advertised gap, and your exact Charger year before purchase.

A-Premium Iridium Platinum 6-Pack

This A-Premium set is not the right pick for a modern 3.6L Pentastar Charger. Its best role in this article is as an older 2006-2010 2.7L V6 Charger option, where the listing provides more relevant fitment language.

Choose it only if your Charger matches the older 2.7L fitment, thread size, and advertised gap. Avoid it for 3.6L V6, 5.7L V8, 6.1L V8, and 6.4L V8 models.

Why You’ll Like It

• Clearer fit for older 2.7L V6 Charger applications
• 6-pack format for a complete V6 service
• Iridium tip and platinum core listing details
• Useful for owners maintaining earlier Charger model years

Check Before Buying

Confirm your engine is the 2.7L V6 and verify the 0.052 inch advertised gap before installing. Do not buy this as a substitute for a 3.6L Pentastar plug.

FAQ

How Do I Choose The Right Spark Plugs For My Dodge Charger?

Start with your exact year and engine. A 3.6L V6 usually needs a 6-plug set, while many 5.7L HEMI applications need 16 plugs because they use two plugs per cylinder. High-output 6.1L and 6.4L V8 models may use different plug specs, and older 2.7L V6 Chargers need their own fitment.

After that, match the plug code, thread size, reach, heat range, and gap to your service manual or fitment listing. Do not choose a plug only because it says “Dodge” or “Charger” in a broad compatibility list.

Are Iridium Spark Plugs Better Than Copper For A Charger?

Iridium plugs usually last longer and hold a stable spark gap better over time, which makes them a strong choice for many daily drivers. Copper plugs can still be a practical choice for older HEMI engines or budget-focused maintenance, but they may need replacement sooner.

The best material depends on your engine, service interval goal, and whether you want the lowest upfront cost or longer wear resistance.

Will New Spark Plugs Improve Performance And Fuel Economy?

New spark plugs can restore lost smoothness, reduce plug-related misfires, improve cold starts, and make throttle response feel cleaner if the old plugs were worn, fouled, or incorrectly gapped. They will not create major horsepower gains by themselves.

If your Charger still runs poorly after the plug change, check ignition coils, boots, fuel delivery, sensors, and stored trouble codes.

What Should I Know Before Installing Spark Plugs Myself?

Work on a cool engine, use the correct spark plug socket, label coils as you remove them, and thread plugs by hand first to avoid cross-threading. Use a torque wrench and follow the correct torque spec for your engine.

Check the gap carefully, but be gentle with fine-wire iridium or platinum tips. If you are unsure about gapping or torque, have a qualified mechanic finish the installation.

Final Recommendation

If you drive a 2011-2020 3.6L V6 Charger, start with the NGK Iridium IX 6-Pack or Champion Iridium 6-Pack. If you drive a 2009-2020 5.7L HEMI, focus on a full 16-pack such as the NGK Laser Iridium, NGK Iridium IX, or Champion Copper Plus set that matches your exact year.

For 6.1L or 6.4L V8 models, use the Champion Platinum 16-pack only after confirming the year-specific gap. For older 2006-2010 2.7L V6 Chargers, the A-Premium set is the better-fit option in this list. Always verify year, engine, plug count, thread size, and gap before you buy.
