Changing plugs

Hi Folks,
I am looking for some step-by-steps or some kind of write up on changing spark plugs. I have searched the threads these past two days and not found quite what I was looking for.

I have a 2004 4.0 manual (as if that matters) and have changed plugs many times on other cars. Just never on my jeep and I am way over due. Does anyone have a link to something like that? Thank you.

It's pretty much the same on all vehicles. I like to blow out the plug holes before I remove the plugs so dirt doesn't fall into the cylinders. Also I use a rubber hose to install the plugs with. This way you can't damage the threads if you were to cross thread one. Do them one at a time so the plug wires don't get messed up.
Just my .02

Here's another write up: Jeep Spark Plug Remove and Install

I second the author's suggestions of anti-seize and dielectric grease. It'll ensure that they never get stuck in the boot or in the block.

As far as plugs go, I use champion brand cheapos, it's not a high performance engine, so it really does not matter.

Same here. I used Champion 7034. Autolite APP985 also work. They are both double platinum plugs. Stay away from single platinum plugs or any of the gimmick plugs.

I agree, both are good choices. I run the autolite APP985's myself. Whatever you do, do NOT put in Bosch plugs that the auto parts stores are always so keen on recommending.

A long 90 degree needle nose pliers help with getting the wire boot off the plug. Do you have an a/c compressor above first plug? If you do, a swivel above the socket will work to remove the plug.
