I am about to replace the spark plugs, and there are a variety of spark plug socket sizes on the market. Which size do I need to complete this job?

Hello, the spark plug size should be a standard 5/8" (16mm) socket. I recommend one with a magnet inside to keep the plug with the socket, and to make installation easier.

Check out our article on tune-ups: https://www.2carpros.com/articles/how-to-tune-up-a-car-engine

The torque for the spark plugs is 12Nm or 8.8ft/lbs. Or just hand tight. After tightening you can give them a little nudge tighter and that will be fine.

I ordered one from Home Depot a couple of days ago that is magnetized.
