^ different for everyone depending on how the vehicle is maintained, how driven, fuel quality, etc.
The only way to really tell is to pull them and take a look. There shouldn't be too much black soot (although most 8's run very rich). Ideally a brownish-tan residue).
Having said that, 12k miles is a good rule of thumb.

its debateable. I would change them every 12k to 15k miles. Depending on their condition, it is cheaper to just clean them. Cleaning them is not my expertise so, you would have to ask others that are more familiar with the process and what all to do/look for.

If its tough to loosen, someone may not have used anti-seize on it last time, so make sure you do when you install your plugs.
Don't use a torque wrench to remove the plugs.
You can use a breaker bar, but it shouldn't require THAT much to loosen the plugs... maybe go work out at the gym

Make sure you're using a 13/16" spark plug socket (not a regular socket).

Was in for an oil change today and just out of curiosity asked how much just to install the plugs I bought (haven't had time to do it myself yet)
$150!... Just for the install I don't get where they came up with that number. Should just be paying for labor which should take maybe 15 min tops for a pro. If it was maybe $25 I would have said go ahead...but geez...$150!?

I zoom therefore I am.
i like to call that the "dont ask us to do this" fee. they either didnt feel comfortable doing it, or had never changed the plugs on a rotary before.. so they're basically throwing out a number they know most people will say no thank you to.

Well, I am close to 90k, so it's about time for that maintenance stuff. I just wanted the oil changed but they seemed pissed I wouldn't let them do the tranny fluid and the other stuff. Thanks to the DIYs on here I am very comfortable doing it on my own and Im not even very mehcanically inclined. Planning on doing the plugs next weekend and Im gonna order some coils this week and do that too. If stealerships wouldn't charge so damn much I'd actually let them do the work, but the prices are just getting out of hand for this stuff. It actually makes me feel really good that I have learned to do all of this stuff on my own. I actually enjoy doing it.

My new spark plugs...
Hey Fellas. I just changed the spark plugs on my car with 40K on the odometer. Boy what a difference it makes. The car idles much smoother and runs like it's supposed to. Anyone waiting to see if they need to change their spark plugs can look at how mine were .
Funny how I always take my car to the dealer for routine maintenance and they never mentioned new plugs. I have new coils and wires on the way.
Thanks for the useful info from everyone. I freakin' love this forum!

I changed my plugs today after reading through this thread a few times. All 4 were easily accessible by removing the drivers wheel, I never had to get under the car. Start to finish was about an hour, and I really didn't try to rush. Thanks for the info here, made the job a piece of cake.
