Swapping out my spark plugs for the first time on this truck, i ordered the sp594 plugs. From everything I've seen that's the correct part number. Should i use the anti seize on the spark plugs? Ive heard some people say yes and some people say no. Do the boots need to be swapped out as well? Any tips or tricks would be awesome, thanks.

I didn’t use anti sieze on the threads. Boots were ok after about 60k. I put a touch of dielectric grease to help the boot slide over the plug.

It’s a pretty easy job other that moving wires to access the coils.

It wont hurt and can help. Haven't installed a plug (including customers) in over 30 years without it. Never had a problem removing one I'd installed.

I appreciate all the replies everyone. Got some good feedback. Going to swap them out this upcoming weekend. Hopefully all goes well.

This is the way.

I use the copper-based grease, and also make sure the very thin layer of anti seize I put on doesn’t get down into the last thread or two before the electrode.
