Best Dodge Dart Spark Plugs: 7 Top Picks Compared

If you drive a Dodge Dart, the right spark plugs can help restore smoother starts, steadier idle and cleaner throttle response, especially if your current plugs are worn, fouled or past their service interval. The key is not just picking a popular plug. You need a set that matches your Dart’s engine, model year, gap, thread style and OE fitment.

This guide compares seven Dodge Dart spark plug options across iridium, platinum and copper designs so you can quickly choose the best match for your engine and budget. Before ordering, confirm your engine size, year, OE number and required gap in your owner’s manual, repair guide or Amazon Garage fitment checker.

Top Picks

How We Chose These Spark Plugs

You want plugs that match your Dart’s engine, deliver reliable combustion and give you a fair lifespan for the price. We prioritized engine-specific compatibility, OE-number clarity, electrode material, thread and gap information, buyer feedback patterns, brand familiarity and overall value.

We also separated 1.4L, 2.0L and 2.4L choices where possible because Dodge Dart spark plug fitment is not one-size-fits-all. Iridium and platinum designs earned extra weight for long service life and consistent spark, while copper plugs were treated as budget-friendly replacements for shoppers who prefer a basic OE-style option.

Before You Buy: Quick Checklist

• Confirm engine size: 1.4L turbo, 2.0L or 2.4L.
• Match the OE number: Use your old plug, owner’s manual or fitment guide as the final reference.
• Check gap and thread: Do not force a plug that does not match your engine’s required specs.
• Use a torque wrench: Over-tightening can damage threads, while under-tightening can cause sealing problems.
• Inspect coils and boots: New plugs will not fix a weak ignition coil, cracked boot or unrelated engine fault.

Who Should Avoid This

Avoid it if your engine calls for a different gap, plug type or OE number, or if you are troubleshooting a misfire that may be caused by coils or wiring rather than plugs.

BDFHYK positions itself as a dedicated auto parts maker with OE-level production claims and a support window. It is a value-oriented choice, so careful pre-install inspection and fitment verification matter more than with a direct OE-name plug.

Champion Iridium Spark Plugs (4 pc)

This Champion iridium-style 4-pack is a strong OE-style option for compatible 2.0L Dodge Dart models. The main appeal is simple: you get a familiar spark plug brand, a direct-replacement positioning and an advertised 0.042 in gap for the listed application.

For everyday driving, this is the kind of plug you consider when you want reliable starts and smooth idling without chasing aggressive performance claims. It is not the most universal pick in this guide, but it is a sensible option if your 2.0L Dart matches the listing.

Why You’ll Like It

• Iridium-style construction for longer life than basic copper plugs
• Pack of four covers a complete service

What People Say

Champion Copper Plus Spark Plugs (4 pc)

If you are servicing a compatible 2.4L Dodge Dart and want a simple copper-core replacement, Champion Copper Plus is the budget-friendly traditional option in this guide. Copper plugs usually cost less than premium iridium or platinum plugs, but they may need replacement sooner depending on use and engine condition.

This set is best for drivers who want predictable OE-style behavior rather than a long-life upgrade. It can help restore smoother starts and steadier idle if your current plugs are worn, but it is not the right choice if your service guide specifically calls for an iridium or platinum plug.

Why You’ll Like It

• Budget-friendly copper-core option for listed 2.4L Dart applications
• Familiar Champion brand
• Pack of four covers a complete tune-up
• Simple choice for routine maintenance when premium materials are not required

Overall Sentiment: Positive

Ease Of Use

Brand Trust

Champion is a familiar spark plug brand, and this listing is positioned as a direct replacement for specified 2.4L Dodge Dart model years.

Who Should Buy This

Choose Champion Copper Plus if you have a matching 2.4L Dart and want a simple, affordable plug from a known brand.

Who Should Avoid This

BDFHYK AP5325 Iridium Spark Plugs (4 pc)

BDFHYK AP5325 is the broad-fit budget alternative in this roundup. It is listed for Dodge Dart 2013–2016 among many other vehicles, so it can be useful if your OE number and engine specs match, but it deserves a more careful fitment check than the narrower Champion, NGK or DENSO listings.

The main reason to consider it is value. You get a four-pack with an iridium center electrode and OE-style construction claims, which may help restore smoother idle and cleaner starts when replacing tired plugs. Because this listing covers many vehicles, do not install it until you confirm AP5325 or the replacement number is correct for your exact Dart.

Why You’ll Like It

• Budget-friendly iridium option
• Listed for Dodge Dart and many other L4 engines
• Set of four covers a complete tune-up
• Useful when you need a lower-cost replacement and fitment checks out

What People Say

Many owners note that the plugs arrive with a usable gap, fit without fuss on listed vehicles and smooth out idle or misfire symptoms when plugs are the actual cause. Because some feedback comes from non-Dart vehicles, Dodge Dart buyers should verify fitment carefully.

Overall Sentiment: Positive

Ease Of Use

Brand Trust

BDFHYK presents itself as an auto-parts maker with production-line and support claims. It is still a value brand, so inspect each plug and verify application details before installing.

Who Should Buy This

Buy BDFHYK AP5325 if your exact Dart application cross-references to AP5325 and you want a lower-cost iridium-style replacement.

Who Should Avoid This

Avoid it if you want the safest direct-fit choice with the least compatibility homework, or if your OE number points to a different plug.

A-Premium Iridium Platinum Spark Plugs (4 pc)

If you drive a Dodge Dart with the 1.4L engine and want a lower-cost iridium/platinum-style option, this A-Premium set is worth considering after you confirm fitment. It comes as a four-pack and is positioned as an OEM-style replacement for the listed 1.4L application.

The benefit is straightforward: replacing worn plugs can help restore cleaner starts, steadier idle and more predictable throttle response. However, this is not the strongest brand-trust pick in the guide, so inspect the plugs, confirm the advertised 0.028″ gap and verify the OE number before installation.

Why You’ll Like It

• Affordable alternative for listed 1.4L Dodge Dart applications
• Iridium tip with platinum core design
• Advertised 0.028″ gap for the listed application
• Pack of four covers a complete service

What People Say

Most source feedback says the plugs arrive ready to install, fit specified engines and can improve smoothness on compatible vehicles. A few fitment or longevity concerns make pre-purchase verification important.

Overall Sentiment: Positive

Ease Of Use

Brand Trust

A-Premium is a third-party parts brand with many listings across common replacement categories. It is best treated as a budget-friendly alternative rather than the first choice for shoppers who prioritize legacy ignition brands.

Who Should Buy This

Choose A-Premium if your 1.4L Dart fitment matches and you want an affordable iridium/platinum-style plug set.

Who Should Avoid This

Skip it if you prefer a major spark plug brand, need the longest proven service life or cannot confirm the advertised gap and OE number.

FAQ

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

Start with your engine size: 1.4L turbo, 2.0L or 2.4L. Then confirm the model year, OE number, thread size, seat type and recommended gap. Dodge Dart listings often overlap with other Chrysler, Fiat, Jeep, Hyundai, Kia or Toyota applications, so a broad compatibility list is not enough by itself.

If you are unsure, remove one old plug and compare the part number, or use your owner’s manual, repair database or trusted fitment checker. The safest spark plug is the one that matches your exact engine, not simply the one with the best review count or strongest marketing copy.

Will Upgrading To Iridium Or Platinum Spark Plugs Improve Performance And Fuel Economy?

Quality iridium or platinum plugs can help restore smoother idle, cleaner starts and more consistent throttle response when old plugs are worn. They may also help maintain efficient combustion over time because precious-metal electrodes tend to last longer than basic copper plugs.

Do not expect a dramatic horsepower gain from spark plugs alone. If your Dart has weak ignition coils, fouled injectors, vacuum leaks, sensor problems or compression issues, new plugs may not solve the underlying problem. Treat plugs as part of a complete tune-up and diagnosis.

Are Copper Spark Plugs Bad For A Dodge Dart?

Copper plugs are not automatically bad, but they are usually a more basic, shorter-service-life option than iridium or platinum. They can make sense when the listing matches your exact engine and you want an affordable OE-style replacement. If your manual or OE cross-reference calls for a precious-metal plug, follow that guidance instead of choosing copper only to save money.

What Are The Best Practices For Installing Spark Plugs In A Dodge Dart?

Work on a cool engine, remove debris around the plug wells, hand-start each plug to avoid cross-threading and use a torque wrench set to the factory specification. Do not rely on feel alone. Over-tightening can damage threads, while under-tightening can cause poor sealing or heat transfer problems.

Avoid heavy anti-seize on plated threads unless the plug maker recommends it. A small amount of dielectric grease inside the coil boot can help with moisture resistance and future removal. Replace all plugs in the same service, inspect coil boots and clear or recheck diagnostic codes after installation.

How Often Should I Replace Dodge Dart Spark Plugs?

Replacement interval depends on plug material, engine condition and driving habits. Copper plugs usually need replacement sooner than iridium or platinum plugs. If you notice rough idle, hard starts, misfires, poor fuel economy or engine codes, inspect the plugs and ignition system even if you have not reached the normal interval.

Drivers Top Picks

When choosing between NGK Iridium IX, DENSO Platinum TT and Champion options, focus on your engine first. NGK is the strongest all-around pick for many 2.0L and 2.4L shoppers, DENSO is a strong performance-minded platinum option, and Champion works well when the specific 2.0L or 2.4L listing matches your Dart.

For 1.4L applications, compare BDFHYK 93618 and A-Premium carefully by OE number and advertised gap. If you want the least guesswork, prioritize the plug with the clearest match to your old plug or service guide.

Wrapping Up

You do not need to guess which spark plugs suit your Dodge Dart. If you want the best all-around option for compatible 2.0L or 2.4L applications, NGK Iridium IX is the top pick. If you want a performance-focused platinum design, DENSO Platinum TT is a strong choice. If you have a matching 1.4L application and want value, BDFHYK 93618 is worth a close look.

Match the plug to your engine size, OE number, thread, gap and budget. When the fitment is right, fresh plugs can help restore smoother starts, reduce ignition roughness and make your Dart feel more consistent during daily driving.
