What is the 2013 chevy sonic spark plug torque?

The 2013 Chevy Sonic should have the spark plugs torqued to 18 ft pounds. Insufficient torque can prevent correct spark plug operation. An over-torqued spark plug, causes the insulator to crack. The OEM spark plugs on this 2013 Sonic are ACDelco part number 41-122 (55585534). Your spark plugs are what supply the spark that ignites the air/fuel mixture, creating the explosion which makes Your engine produce power. These small but simple plugs create an arc of electricity across two leads that are not touching, but close enough together that electricity can jump the gap between them.Spark plugs will deteriorate over time, so if they are not replaced, various engine issues will arise. When the spark plugs do not spark adequately, the combustion of the air/fuel mixture becomes incomplete leading to loss of engine power, and in the worst-case scenario, the engine will not run.
