Comparison and Buying Insights

Choosing the right spark plug depends entirely on your Journey’s engine and your driving habits. Here are a few key insights to help you decide which are the best spark plugs for dodge journey reliability.

Engine Specificity is Crucial: Always start by confirming your engine type. The popular 3.6L V6 uses 6 plugs and often demands iridium or double platinum (like the 6 pc Champion Iridium or the 6 pc NGK Iridium IX). The smaller 2.4L L4 engine, however, performs exceptionally well with high-quality copper plugs due to its design constraints and lower operating temperatures.

Longevity vs. Conductivity: If you prioritize long-term maintenance intervals (100,000+ miles), Iridium is the clear winner. The NGK Iridium IX and Champion Iridium are your top choices. If you prioritize peak electrical conductivity and initial punch and don’t mind changing the plugs every 30,000 miles, the Champion Copper Plus is excellent for the 2.4L model.

Value in Platinum: For the 3.6L V6, the Autolite Double Platinum provides phenomenal value. Double Platinum technology is almost as durable as iridium but is often less expensive, making it a great choice for balancing budget and long service life.

OEM Preference: Since Champion is a major Mopar OE supplier, sticking with Champion parts often guarantees the correct heat range and perfect fitment, especially for the 3.5L and 3.6L V6 models.

Final Verdict

If you drive the most common version, the 3.6L V6, the choice between Champion Iridium, NGK Iridium, and Autolite Double Platinum comes down to brand loyalty and slight performance preference.

Our Overall Recommendation for 3.6L V6: The 6 pc Champion Iridium Spark Plugs win for being the most reliable, tested, and high-quality OE-style replacement that guarantees longevity and performance.

Best for Performance & Longevity: If budget isn’t the primary concern and you want the highest precision, go with the 6 pc NGK Iridium IX Spark Plugs.

Best for the 2.4L (Value & Conductivity): The 4 pc Champion Copper Plus Spark Plugs offer the best initial spark and conductivity for the smaller engine, provided you respect the shorter replacement intervals.

Best Spark Plugs For Dodge Journey FAQ

Q: What is the recommended service interval for spark plugs in a Dodge Journey?

A: The service interval depends heavily on the plug material and engine type. Most modern Dodge Journey models (especially those with the 3.6L V6 using Iridium plugs) recommend replacement at around 100,000 miles. If you use high-quality Copper plugs (like the Champion Copper Plus in the 2.4L), the interval drops significantly, typically requiring replacement every 30,000 miles. Always check your owner’s manual for specific instructions.

Q: Should I choose Iridium, Platinum, or Copper spark plugs for my Journey?

A: It depends on your engine and priorities. Iridium offers the longest life (best longevity) and highest heat resistance, making it ideal for the 3.6L V6. Double Platinum offers great longevity and value, effectively resisting wear in coil-on-plug systems. Copper offers the best electrical conductivity and power but has the shortest lifespan, making it suitable for the 2.4L engine if you maintain it often.

Q: Do I need to gap the best spark plugs for dodge journey before installing them?

A: While most modern platinum or iridium plugs (like the NGK Iridium IX or Champion Iridium) are “pre-gapped” from the factory, it is always recommended to double-check the gap against your Dodge Journey’s specifications (usually found on a sticker under the hood or in the owner’s manual). Handling and shipping can sometimes cause the gap to shift, leading to misfires if installed incorrectly.

Q: Can old spark plugs affect my Dodge Journey’s fuel economy?

A: Yes, absolutely. Worn-out spark plugs that cause weak or inconsistent sparks result in incomplete combustion. This means your engine wastes fuel and produces less power. Replacing old plugs with a fresh set of the best spark plugs for dodge journey can often lead to a noticeable improvement in MPG and overall performance.

Q: Why are there only 4 plugs reviewed for the 2.4L engine, but 6 for the V6?

A: The Dodge Journey comes with two primary engine types. The 2.4L engine is an inline four-cylinder (L4), requiring four spark plugs. The 3.5L and 3.6L engines are six-cylinder V-shaped engines (V6), requiring six spark plugs. Always buy the correct number of spark plugs for your specific engine configuration.

Q: Will using the wrong heat range of spark plug cause damage?

A: Yes, using a plug with the incorrect heat range can be detrimental. A plug that is too “hot” (retains too much heat) can cause pre-ignition and engine damage, while a plug that is too “cold” (dissipates heat too quickly) can lead to plug fouling and misfires. Always choose plugs (like the tested Champion and NGK options) that are specifically designed for your Dodge Journey’s engine year and model to ensure the correct factory heat range.
