How many spark plugs does a 2003 Dodge Ram 1500 have?

In short, it depends on the engine. Most 2003 Ram 1500s use eight spark plugs, but the 5.7-liter Hemi adds a second spark plug per cylinder for a total of sixteen.


Engine options in the 2003 Ram 1500


During the 2003 model year, the Ram 1500 offered several V8 powerplants, including traditional Magnum designs and Chrysler's Hemi. The main options were the 4.7L Magnum V8, the 5.9L Magnum V8, and the 5.7L Hemi, with availability varying by trim and region.



  • 4.7L Magnum V8

  • 5.9L Magnum V8

  • 5.7L Hemi


Because spark plug count tracks with the engine architecture, the plug count for these engines is 8 for the 4.7L and 5.9L Magnum, and 16 for the 5.7L Hemi.


Spark plug counts by engine


Here is a quick tally showing how many spark plugs each engine typically uses in the 2003 Ram 1500 lineup. Note that some late-builds or unique configurations could differ.

  • 5.9L Magnum V8 — 8 spark plugs (one per cylinder)

  • 5.7L Hemi — 16 spark plugs (two per cylinder)


In short, the number of spark plugs you have depends on the installed engine; if your truck runs the Hemi, expect 16; otherwise, eight.
