i have a question i have tried 5/8 socket and 13/16 socket 5/8 isnt big enough and the 13/16 is to fat to fit down the hole so what do i use to get the spark plug out or what size socket should work........

18mm fits the plug, but some sockets are too large to fit in the hole so you may have to grind it down

Or if you have the stock tool set the spark plug socket works perfectly.

you can also buy skinny neck sockets. thats what we did and it fit perfect.
