So how hard is the change? Mine are still stock and all this talk makes me want to swap them out. Just did the set on my son's '02 Ford Ranger and they were AWFUL to change (like having to pull the passenger tire/wheel well to get to the back two). Bad enough to pay someone or pretty easy?

It's really not that hard of a job.  There's a good how to with pictures in the how to section that should help.  Shouldn't take you more than an hour as long as the boots come off easy.  I had a little issue with the coil boots getting stuck on the plug when removing mine.  Other than that, it's fairly straightforward.  It would probably take me a half hour now that I've already done it once.  Don't forget to grease your coils and use some anti-seize on the threads when installing the new plugs.

If you use antiseize, use a minimal amount, a tiny dab vertically striped across the plug threads.  That will then distribute itself over the threads as you install the plug, without changing torquing specs.

Changed the plugs to Ford SP534 in anticipation of my LMS tunes which hopefully will be here today. Out of the box they were gapped between .30 and .34,  I went ahead and set the gap to .30.  Took roughly an hour and a half to change the plugs and I only broke 1 red clip. Big hands and transverse motors don't get along too well.  Factory plugs were all over the place from .33 all the way up to .38.

Might be a placebo effect, but the car already seems to run a little better.

Yeah, those red clips work well, but are really annoying the first few times ...
