yea i figured it was as easy as it sounds but someone told me to watch out on how i put them in, that i have to do it a certain way or i risk breaking them. I thought he mant like i had to put them back in the same order that i took them out, just confused.

not the plugs themselves but the wires need to go exactly where you found them.

You should torque the plugs down to a specific number but that's a meme, tighten them so they are tight but not too tight that you need a breaker bar to get them loose again.

What they proably meant is don't bang them around as with some electrode materials are extermly fragile and will break similar thing will happen with the arm or whatever it's real name is but with all plug if you bang it around you risk messing up the gap. Most plugs come pre gapped but I like to double check them and make sure there correct and similar you can get the gapper at any auto parts store there usually at the counter just ask there a little disk about the shape of a silver dollar but the rim is beveled with the measurements ontop there like a dollar to 10 depends on the brand
