Why change the spark plugs?
Changing the spark plugs on your Dodge Durango at the recommended 100,000-mile mark is important to avoid engine problems. Old spark plugs may cause poor fuel economy as well. Engine misfire is one common sign of old spark plugs.
Replacement Cost
It costs between $280 to $500 to replace the spark plugs on a 2011 to 2017 Dodge Durango. It is more expensive than most cars because the intake plenum on top of the engine needs to be replaced.
This requires one to two hours of extra work, which is why shops will charge you more to replace the spark plugs on a 3.6 Dodge Durango with the Pentastar engine.
Replacement Interval
Based on the owner’s manual, the spark plugs on the 3.6l V6 Pentastar engine should be changed every 100,000 miles. Only use platinum or iridium spark plugs. If you decide to install copper spark plugs, they must be replaced every 30,000 miles.
If you need to reset the check engine light on your dashboard, you will need the YOUCANIC Full System Scanner to clear the fault code after replacing the spark plugs and ignition coil of your Dodge 3.6L V6.
