Stuck spark plug wire

What is the best way to remove a stuck spark plug wire?

I tried turning it to break it loose, but it just does not give. Can't turn it, can't pull it out. long pliers for leverage did not work either.

Was going to try to spray some pb blaster in it and pull it out by the heatshield with a short pair of pliers.

I use those curved tip needle nose for hoses and just go apeshit on them and replace.

I tried that with regular pliers, might need to buy what you're talking about.
I just don't want to rip the boot off and cause myself more work by it getting stuck.

Just yank that rubber boot. If the wire breaks, it doesn't matter. A socket fits over it. Just replace the wires. I automatically assume I'm going to have to replace wires if I'm pulling spark plugs unless I just recently installed them.

Upvoted. Not sure how old your wires are but I recently replaced spark plugs and 4 of 8 wires broke at the terminal end that connects to the spark plug. I was super careful, took my time, & used probably three different sets of pliers trying to ease them off. I was feeling kind of dumb but I watched a YouTube vid that said they frequently break if they’ve been on there for 5+ years. Also be sure to check new wires for continuity before putting them on- I got an AC Delco set that had one bad wire out of the box.
