Hey guys i was looking around for a diy on a JK spark plug change and couldn't really find any thing so here you go! ( if you feel like i missed anything please add to the post!)
Tools needed: 3/8th wrench or 1/2 in wrench
8 in extension, 5 in extension
5/8 spark plug socket
3/8 swivel (your new best friend)
Parts needed: 6 NGK G-power plugs (or whatever you perfer) $18
Anti Seize $1.29
I started with the easy side first un-pluged the wires a pushed to the side and
with one easy twist with the 1/2 wrench with 8 in extension and 5/8 socket and it was loose and kept spinning until i could untwist by hand.
slapped some anti-seize on the new plugs and installed them. (tightened all the
way then half a turn) or you can go by the torque measurements on the back of
the box 13 ft lbs.
after i was done with the driver side i started on the passenger side, i removed the air intake hose from the box to the engine (gives you a lot of wiggle room)
and disconnected the 2 vacuum hoses from clamp and pushed them to the side that cover up the passenger side plugs. (ill post more pics, just bare with me)
grab your 1/2 wrench and 8 in extension with the swivel and 5/8 socket attached and connect to the plug and lean it against the battery wall (sweet spot to remove the #5 plug and turn to the left and ta-da its loose, remove that plug and slap on some anti seize to the new plug and reinstall opposite on how you removed it. i stuck the new plug in by hand first tightening enough before i used the wrench (helps sooo much) re connected all spark plug wires, hoses, and grab a cold one.
