The spark plug gap for a 2016 Honda Civic is typically about 0.043 inches (1.1 mm), though the exact setting depends on engine variant and the plug type you’re using.
Engine variants and gap specifications
In 2016, the Civic offered at least two common engine configurations in many markets: a 2.0-liter i-VTEC four-cylinder and a 1.5-liter turbocharged four-cylinder. Each engine variant has a recommended gap range for the plugs that Honda and plug manufacturers specify. Always verify the exact gap on the plug you’re installing or consulting the official service manual for your VIN.
2.0-liter i-VTEC engine
For the 2.0-liter i-VTEC engine, the typical recommended spark plug gap is 0.043 inches (1.1 mm) for standard OEM plugs such as iridium or platinum types. If you’re using a different plug type, confirm the gap on the packaging or in the manual.
1.5-liter turbo engine
For the 1.5-liter turbocharged engine, the gap is commonly around 0.043–0.044 inches (1.1–1.12 mm). Many OEM replacements come pre-gapped to about 0.043 inches, but it’s best to double-check the exact specification on the plug packaging or in Honda’s service documentation.
To ensure accuracy, always refer to the exact spark plug package or the Honda service data for your specific model/year and VIN, since gaps can vary slightly by plug type and market.
- 2.0-liter i-VTEC: 0.043 inches (1.1 mm)
- 1.5-liter turbo: 0.043–0.044 inches (1.1–1.12 mm)
