What is the spark plug gap on a 2013 Dodge Avenger?
For the 2013 Dodge Avenger, the typical factory spark plug gap is 0.040 inches (1.0 mm).
The 2013 Avenger offered two engines—the 2.4-liter Tigershark inline-four and the 3.6-liter Pentastar V6. In most cases, modern OEM plugs for these engines are gapped to 0.040 inches (1.0 mm). However, the exact gap can vary slightly depending on the plug type (iridium, platinum, or copper) and the manufacturer’s specifications. Always confirm the correct gap for your specific plug model in the owner's manual or the plug manufacturer's guidance, and re-check the gap after replacing plugs.
Engine options and spark plug gap
Typical factory gap values by engine are listed below to guide replacement decisions.
- 2.4L Tigershark I4: 0.040 inches (1.0 mm).
- 3.6L Pentastar V6: 0.040 inches (1.0 mm).
Note: While 0.040 inches is a common target for factory-rated plugs on these engines, some plug brands or types may have different pre-set gaps. Always cross-check the exact gap specification from the plug packaging or the vehicle’s service information before installation.
How to check and adjust the spark plug gap
To ensure the correct gap and reliable ignition, follow these practical steps before and after a plug replacement.
- Prepare your tools: spark plug socket, torque wrench, feeler gauge, and the appropriate replacement plugs.
- Ensure the engine is cool and disconnect the negative battery terminal to avoid any electrical issues.
- Remove the spark plug from the cylinder using the correct socket and extension. Inspect the plug for wear or damage.
- Measure the gap with a feeler gauge and compare it to 0.040 inches (1.0 mm). If out of spec, adjust the gap carefully by bending the ground electrode (only if the plug design allows) or replace with a plug pre-gapped to the correct specification.
- Reinstall the plug and torque to the manufacturer’s specification, reconnect the ignition coil/wiring, and repeat for all cylinders. Start the engine and check for smooth operation and absence of misfires.
Pro tip: If you buy pre-gapped plugs, double-check the gap again before installation, as handling and transit can cause small shifts. Always refer to the plug maker’s guidance and the vehicle’s manual for final torque recommendations.
Summary
The spark plug gap for a 2013 Dodge Avenger is typically 0.040 inches (1.0 mm) for both the 2.4L Tigershark I4 and the 3.6L Pentastar V6, though you should verify the exact gap for your chosen plug type and engine in the owner’s manual or the plug manufacturer’s specifications. When replacing plugs, ensure proper gap, use the correct plug type, and torque to the vehicle’s service manual to maintain performance and emissions compliance.
