Comparison Insights on Best Spark Plugs For Dodge Dart

When selecting the best spark plugs for dodge dart, your choice depends heavily on your specific engine and priorities.

If you own the 2.4L or 2.0L naturally aspirated engine, you have flexibility. The NGK Iridium IX plugs offer the best combination of performance and low maintenance, requiring replacement less often than the alternatives. However, the Champion Copper Plus offers the best value and raw spark power for those who don’t mind changing plugs every 30,000 miles or less.

For the 1.4L Turbo engine, you must use a precious metal plug, as copper cannot handle the heat demands. Both the A-Premium and BDFHYK 93618 plugs are excellent choices, providing the necessary Platinum/Iridium durability. Always double-check the specified 0.028″ gap if you are changing plugs in the 1.4L turbo.

Finally, if you have a 2.4L engine and are experiencing misfires or hesitation that plugs alone won’t fix, the A-Premium Coil Pack and Plug kit offers the most comprehensive solution by refreshing the entire ignition chain at once.

Final Verdict: Choosing Your Spark Plug Champion

Making the right choice depends on your Dart’s engine and your driving habits. Here is a quick reference guide:

Best Overall (2.4L/2.0L): The 4 pc NGK Iridium IX Spark Plugs wins for longevity, fuel efficiency benefits, and general reliability, making it the top “set-it-and-forget-it” option.

Best for Turbocharged Engines (1.4L): Choose the A-Premium Iridium Platinum Spark Plugs (Reference 93618). Their specific engineering for high-heat, forced-induction applications ensures the highest performance and durability for your sensitive turbo motor.

Best Value/Performance (2.4L): The 4 pc Champion Copper Plus Spark Plugs are unbeatable if you need maximum spark conductivity and low cost, provided you commit to more frequent replacements.

Best Spark Plugs For Dodge Dart FAQ

Q1: What is the recommended service interval for spark plugs in the Dodge Dart?

A: This depends on the plug material. If you install Iridium or Platinum plugs (which are considered the best spark plugs for dodge dart for longevity), you can typically expect them to last between 80,000 and 100,000 miles. Copper plugs, however, should be replaced much sooner, usually every 30,000 miles to maintain optimal engine performance.

Q2: Do the 1.4L Turbo and 2.4L engines use the same spark plugs?

A: No, they require completely different spark plugs due to the difference in compression and cylinder heat. The 1.4L Turbo requires a smaller gap (typically 0.028 inches) and highly durable materials like Platinum or Iridium to withstand forced induction stress. The 2.4L uses a different plug specification and gap. Always confirm your Dodge Dart maintenance parts by engine size.

Q3: What are the signs that I need to replace my spark plugs?

A: Common symptoms include rough idling (the engine shakes slightly when stationary), difficulty starting, poor acceleration or noticeable hesitation, and a decrease in fuel economy. In severe cases, you may also get a “Check Engine” light indicating a specific cylinder misfire.

Q4: Should I use copper, platinum, or iridium spark plugs for my Dodge Dart?

A: For daily drivers seeking the best performance longevity and minimizing maintenance, iridium or platinum plugs are highly recommended (such as the NGK or A-Premium options reviewed). Copper offers a strong initial spark but requires much more frequent replacement. Precious metal plugs are crucial for the 1.4L turbo engine.

Q5: What is the correct plug gap specification for the Dodge Dart?

A: The correct plug gap specification varies by engine. For the 1.4L Turbo, the gap is typically very tight, around 0.028 inches. For the 2.4L, the gap is usually larger, around 0.044 inches. It is essential to confirm the precise gap in your owner’s manual or on the OEM reference card, even if the plugs are “pre-gapped.”

Q6: Can poor spark plugs affect my gas mileage?

A: Absolutely. Worn or fouled spark plugs lead to inefficient combustion, meaning the engine has to work harder to maintain speed. Replacing worn plugs with the best spark plugs for dodge dart (especially precious metals like Iridium) can significantly restore lost fuel efficiency.

Q7: Is replacing the spark plugs on a Dodge Dart a difficult DIY task?

A: For most Dart models, replacing the plugs is a relatively straightforward DIY job, requiring basic tools like a torque wrench, spark plug socket, and extensions. The spark plugs are located under the coil packs, which are easily accessible on top of the engine valve cover.
