What is the spark plug gap on a 2014 Dodge Charger?
For a 2014 Charger, spark plug gap depends on the engine. The 3.6-liter V6 typically calls for a 0.040-inch gap, while the 5.7-liter Hemi and the 6.4-liter Hemi generally require about 0.043 inches. Always verify the exact gap from the factory service manual or the plug manufacturer for your specific engine and plug type.
Engine-by-engine gap specifications
The following specs reflect common factory recommendations for the 2014 Charger’s engines. These figures assume you’re using the correct plug type (OEM-equivalent copper, platinum, or iridium) and standard compression. If you install aftermarket plugs, confirm the gap with the plug manufacturer.
- 3.6L Pentastar V6 (base/RT) — gap: 0.040 in (1.0 mm).
- 5.7L Hemi V8 — gap: 0.043 in (1.1 mm).
- 6.4L SRT Hemi — gap: 0.043 in (1.1 mm).
Note that some service guides may list a slightly different tolerance or require a specific plug type; always consult the exact factory service manual for your vehicle's VIN and engine code.
Why gap matters
The spark plug gap determines the voltage required to create a spark and the flame kernel size that starts combustion. A gap that is too wide can cause misfires and harder starting, while a gap that is too narrow can reduce heat range and efficiency. For high-performance engines like the 5.7L and 6.4L, precise gaps help maintain optimal ignition timing and combustion stability.
How to measure and adjust the gap
Before adjusting, verify you have the correct plug type and tool. Use a calibrated spark plug gap gauge and follow safe procedures to set the gap to the target specification.
- Remove the spark plug and inspect for wear; replace if worn or damaged.
- Check the current gap with a gauge; compare to the target 0.040 in or 0.043 in as applicable.
- If the gap is off, carefully bend the ground electrode or replace the plug to the target gap.
- Reinstall with the recommended torque for your plug type and engine (verify in the service manual).
- Re-gap plugs if required only when they are cold, and avoid gap-ting-heating plugs while hot.
Always verify torque specs and anti-seize recommendations in the owner's manual or service guide, and re-check the gap after installation.
Summary
In short, spark plug gaps for a 2014 Dodge Charger depend on the engine. The 3.6L V6 uses about 0.040 inches, while the 5.7L and 6.4L V8s use about 0.043 inches. Always confirm with the exact engine specification and spark plug type, and follow the service manual when replacing plugs to ensure proper performance and reliability.
