The Dodge RAM 1500 4.7L has a simple set of 8 Spark plugs. From 1999 to 2008 4.7L Powertech V8 engines had 8 spark plugs and from 2008 to 2013 most of the design shifted to 16 spark plugs.
To be precise, the first-generation 4.7L Dodge Ram 1500 (2007 and older), has 8 spark plugs. The second-generation 4.7L (2008 and newer), has 16 spark plugs.
What Kind of Spark Plugs Does the Dodge 1500 4.7L Use?
The most popular and standard spark plug used for Dodge 1500 is NGK 2262 Platinum Spark Plug ZFR5F-11. The spark plug is protected by transition metals, a sort of metal coating.
Why Does a Second-Generation Dodge Ram 1500 4.7l Engine Have 16 Spark Plugs? How Does It Work?
An ignition coil pack is installed over one spark plug in each chamber, and a standard plug wire is linked to the other spark plug. Furthermore, the coil pack is connected to a plug cable that connects to the opposite chamber side. Each of the chambers is connected to another by a coil pack.
The separate coil fires each of the two plugs on a single-piston. One stopper is directly linked to a coil, while the other is lit through an ignition wire connected to a ring to the cylinder on the opposite bank. During the power stroke, the additional spark plug ignites to burn the hydrocarbons.
A second ignition allows for more power in the downstroke while reducing the requirement for a limiting catalyst. Basically, the dual plug setups will work to generate more efficient combustion, especially with the limited mixtures.
When Should the Spark Plugs of The Dodge Ram 4.7l Be Changed?
It is essential to change the spark plugs after a certain amount of time has passed. My recommendation on the 4.7L would be that the 8 plugs on top are regular copper plugs, and should be changed after every 30k miles.
How Many Spark Plugs Does a 2003 Dodge Ram 1500 5.7L Hemi Have?

Conclusion
The Dodge Ram 1500 4.7L has both 8 and16 spark plugs variants. Mostly the second generation engines have more spark plugs so that they can generate more ignition and power from the engines. It is not necessary that all the second generation models of Dodge RAM 1500 4.7L have 16 spark.
