The number of spark plugs on a 2009 Dodge Journey depends on the engine: four if it's the 2.4-liter four-cylinder, or six if it's the 3.5-liter V6.
In 2009, Dodge offered two gasoline engines for the Journey. Each engine uses one spark plug per cylinder, so the total comes from the number of cylinders in the selected powerplant.

Generally, it's recommended that you have all the spark plugs (one for every engine cylinder) replaced at the same time.
What kills spark plugs quickly?
Pre-ignition can lead to heat building up in the combustion chamber causing the spark plugs to fail. In addition, if the cooling system isn't functioning correctly, it can cause the engine and spark plugs to overheat. This overheating can lead to the spark plug's electrode wearing out faster.
