Were my spark plugs very bad? This is one from the driver side. They all look pretty similar. I checked the gap one of them and it was .057 or so, which I thought was odd. We're going to finish the passenger side tomorrow.

I usually replace my wires about every 35-40k. Prob a little early but I just do it anyways. Another vote for ngk iridiums as well. Unless your gonna run nitrous then go with TR6s

That plug is absolute trash and any other opinion is wrong, no offense to anyone. Iridium is snake oil and there is no reason for it, get some $2.09 AC delco plugs or the cheap Bosch's etc and you will be fine for a looong time to come. Upgrading spark plugs is an age-old folly, it's a simple device that performs a simple job no matter how much you try to advance it by changing the metals that support the spark.
How long do MSD wires last? The same as stockers, barring catastrophe they can quite possibly be good for as long as you own your car. Unless you have over 100,000 miles on them plug wires should not be considered preventative maintenance, especially on an LSx engine with such a short wire.

Honestly, there is no definite "plug life" unless you have a boosted or sprayed engine. Maybe a really high compression race engine as well. Any tame DD car could have their plugs last indefinitely. I would change them between 30k and 50k most likely, but check them periodically before that. Plug wires on the other hand shouldn't need replaced unless the insulation starts cracking, boots come off, get up against a header etc.
Some people will always tell you "replace it periodically, it's cheap insurance" but that doesn't mean that's the best advice. I saw a thread not long ago where someone gave intervals for changing the starter, alternator, and water pump periodically as preventative maintenance
If it ain't broke, don't fix it. Lubes and filters and such obviously need to be changed periodically, but that's a whole different category.
