For the 2014 Equinox, spark plug gap depends on the engine. The 2.4-liter inline-4 uses a gap of about 0.040 inches, while the 3.6-liter V6 uses about 0.060 inches.
In detail, the 2014 model year offered two engines: a 2.4L four-cylinder and a 3.6L V6. The exact gap can vary with plug type (copper, platinum, or iridium) and any GM service bulletins. Always verify the specification in the official GM service information or the owner's manual for your specific vehicle and plug type.
Engine options and their spark plug gaps
The following values reflect the factory recommendations often cited for stock spark plugs installed at the factory. If you use aftermarket plugs, check the packaging or consult a GM service bulletin, as gaps can differ by plug design.

How to verify and set spark plug gap
If you are replacing plugs, use a flat feeler gauge to check the gap before installation. Compare the gap to the factory specification for your engine and plug type, and adjust or replace as needed. When in doubt, refer to the GM service manual for your VIN or contact a dealer service department.
