Changing my 4.7 plugs this weekend I know I need a slim spark plug socket because a normal won't fit. Anything else I need to know or I will need before I do it thanks in advance

After you remove the coils but before removing the plug, use some compressed air to clean dirt out, you don't want that stuff falling into the engine. Also put some high temp anti seize on the plugs so they're easier to remove next time.

Aluminum heads: don't over tighten. Use an extension that grips the socket better than the socket grips the plug or you'll be fishing the socket out with needle nosed pliers. Do one in front first so you'll know for sure if the socket grip is right. Getting it back out of #7 or #8 is a PITA.

Should be .040. I believe it is also labeled under your hood
