How many spark plugs are in a Dodge Challenger?
The number depends on the engine: six spark plugs are used in the 3.6L V6 models, while eight spark plugs are used in all V8 variants (5.7L, 6.4L, and 6.2L supercharged). This reflects one spark plug per cylinder in each engine configuration.
Engine options and spark plug counts

Conclusion: The V6 variant uses six spark plugs.
V8 engines
Challenger models with V8 powertrains — including the 5.7L Hemi, 6.4L Hemi, and the 6.2L supercharged Hemi (Hellcat/Redeye) — are eight-cylinder units, requiring eight spark plugs total.
Spark plug counts for these engines:
- 5.7L Hemi V8 — 8 spark plugs
- 6.4L Hemi V8 — 8 spark plugs
- 6.2L Supercharged Hemi (Hellcat/Redeye) — 8 spark plugs
Conclusion: All V8 Challenger variants use eight spark plugs.
Summary
In summary, the Dodge Challenger uses either six or eight spark plugs depending on the engine. The base 3.6L V6 requires six plugs, while every V8 variant requires eight plugs. This aligns with the standard design of one spark plug per cylinder in modern engines.
