What is the spark plug gap on a 2013 Chevy Sonic?
The spark plug gap for a 2013 Chevy Sonic is typically 0.040 inches (1.0 mm). This baseline applies to the two engines used that year—the 1.8-liter and the 1.4-liter turbo—but the exact gap can vary with plug type. Always verify the specification from the plug manufacturer or the vehicle’s service manual for your exact engine and plug choice.
Engine options and typical gap
Two engines were offered in the 2013 Sonic: a 1.8L I4 and a 1.4L turbo. In practice, replacement plugs commonly use the same nominal gap, but some plug lines or heat-range variants may call for slight deviations. Use the plug maker’s specification or GM service information for the precise value for your engine code.
- 1.8L engine: typical gap around 0.040 in (1.0 mm) for common iridium or platinum plugs; verify if using a different brand or copper-core plugs.
- 1.4L turbo engine: typical gap around 0.040 in (1.0 mm); some plug lines specify 0.040–0.043 in depending on design.
Bottom line: rely on the exact specification printed on the plug you intend to install or the GM service bulletin for your engine code.
Practical tips and cautions
When replacing plugs, always confirm the gap with a precise feeler gauge before installation, and torque plugs to GM’s recommended specification to avoid thread damage or poor compression. If unsure, consult a technician or reference the official GM service information for your VIN and engine code.
How to check and set the gap
Guidance to measure and adjust the gap accurately and safely:
- Choose the correct spark plugs for your Sonic’s engine variant and heat range.
- Remove the old plugs and inspect for wear, fouling, or damage.
- Measure the gap with a feeler gauge set to 0.040 inches (1.0 mm). If needed, carefully adjust by bending the ground electrode only; avoid touching the center electrode.
- Install plugs and tighten to GM’s recommended torque; ensure clean threads and no cross-threading.
- Reconnect ignition components and test engine operation.
For best results, confirm the exact gap and torque from GM’s official service information for your engine code.
Summary
In short, the common spark plug gap for a 2013 Chevy Sonic is 0.040 inches (1.0 mm). Verify the exact value for your engine (1.8L or 1.4L turbo) and chosen plug by checking the plug packaging or GM service information. Using the correct gap, plug type, and installation torque is essential for reliable starts and efficient combustion.
