What is the spark plug gap on a 2006 Dodge Charger?
The spark plug gap for a 2006 Dodge Charger is typically 0.040 inches (1.0 mm), but the exact specification can vary by engine and plug type. Always verify against the specific engine in your car and the spark plug you’re using.
Engine variations and gap specifications
The 2006 Charger was offered with multiple engines, and the factory gap can differ slightly depending on the spark plug and application. The most common target gap for these engines is 0.040 inches (1.0 mm). Below is a straightforward guide by engine type to help you confirm what to set.
- 2.7L V6 (2006): spark plug gap typically 0.040 in (1.0 mm)
- 3.5L V6 (2006): spark plug gap typically 0.040 in (1.0 mm)
- 5.7L Hemi (2006 Charger R/T): spark plug gap typically 0.040 in (1.0 mm)
In practice, many replacement plugs used in these engines are packaged with a recommended gap around 0.040 in (1.0 mm). If your plugs specify a different gap, adjust accordingly—but do not exceed the manufacturer’s recommended specification for your engine.
How to verify and set the gap
To ensure the gap is correct, follow a simple check-and-adjust process before installation or when replacing spark plugs.
- Identify your exact engine and the spark plug part number you’re using (2.7L, 3.5L, or 5.7L Hemi). This determines the correct gap.
- Refer to the plug packaging or the service manual for the recommended gap for that plug and engine; confirm it is 0.040 inches (1.0 mm) if no exception is noted.
- Use a proper feeler gauge to measure the plug gap. If the gap is off, carefully bend the center electrode or adjust with the manufacturer’s recommended method to reach 0.040 inches (1.0 mm).
- Reinstall plugs to the correct torque specification (typically around 11–15 ft-lb for many Mopar plugs, but check your manual).
Concluding notes: Always gap to the exact specification provided for your plug and engine combination. Using too large or too small a gap can affect ignition performance and fuel economy, especially in older engines like the 2006 Charger.
What to do if you’re unsure
If you don’t have the service manual handy, consult the plug packaging or contact a dealership or trusted auto parts retailer with your vehicle’s exact engine code. They can confirm the correct gap for the spark plugs you plan to use.
Summary of the takeaway
For a 2006 Dodge Charger, the typical spark plug gap you’ll want to set is 0.040 inches (1.0 mm), but always confirm for your specific engine and plug type. Accurate gap setting helps maintain ignition performance, fuel efficiency, and overall engine health across the Charger lineup from that year.
