What size Spark Plug socket?
Hi,
I have a 2021 F-150 with the 5.0. What size spark plug socket should I use. I don't have a proper spark plug socket so I want to order one. When I try a standard socket both the 9/16 and the 14mm seemed to have a lot of play. Curious if a purpose built spark plug sprocket will be tighter.

Not sure on size but when you order recommend getting one of the magnetic ones instead of the old school sockets with the rubber boot inside. Those tend to slide out and stay stuck to the plug sometimes. Not a problem with the magnetic sockets. Just my 2 cents. Carry on.
