Replaced the plugs and coils yesterday. Definitely had not been done before, and the car is at 60k miles. Plugs were disgusting and 3/4 of the coils had white marks on them. Car starts, idles, and runs much smoother now.

pfft.. i've done a lot of wrenching on my car. but i'm at the point in my life where my cost per hour is much higher then what i have to pay someone to do it for me.
the one thing i avoid like the plauge is running wires, i'm getting to old to do the "whole body twist" to reach some areas and besides, my audio installer has a very nice movie room to relax in while i wait

just only so few do. my talon eats plugs as well. Most complain of eating plugs due to being 20 bucks a piece. NGKs in my talon are just 3 or so. They dont eat oil either. They do use some depending on load and rpms. Of all the fussing I have heard about, most people dont realize that piston engines eat oil as well. They just do it more as the rings wear. They do eat oil between changes but they dont eat quite as much as the rotary due to design. Remember, the first rings on a piston are called oil control rings for a reason. they control oil residue to keep the cylinder walls lined with a slight coating to keep the rings from diggin in to the walls.
Changing out the plugs is fairly easy once you do it a few times. Just taking off the driver's side tire is the hard part really. I have changed out 5 sets of plugs on my car and do it in about 30 mins or so now. Piston engine owners are so lazy LOL
by the way, I change out my talon plugs every 10k miles or so. turbo has its advantages and disadvantages.

114-156 in- lbf or roughly 10 f-lbf. Overtight can strip the housings 
I just use little motor oil on threads, wipe off excess and tighten little over finger. Never actually measured it

so hand tight is fine?
i thought it would be a large amount of ft/lb due to the fact they can be difficult to remove.. i guess its cuz theyre more stuck on then tight on

A little more than hand tight.
Once you get it hand tight, use the spark plug socket and give the plug another 1/4 - 1/2 turn.
Also remember to use anti-seize on the plug threads so its not so difficult to get out next time.

what spark plugs are good?
DENSO ULTIMATE CLASS IRIDIUM RACING SPARK PLUG, are these good plugs for the rx-8? i found them on autopartswarehouse.com/ they are $51 each, so i was curious if they were worth the money?

Well boys and girls I made it 75,000mi on the original plugs before they went on me two days ago, been premixing since she was born as well what ever that helps.
Thanks for thread helped out a bunch on my install today she runs great now

rx7 plugs
Not in particular. Best is to find some way of disabling spark and fuel - probably pulling the ECU fuse or the like, then cranking the engine over for a second or so to blow all the fuel vapor out.
You have to be REALLY careful with this, as atomized fuel is VERY flammable. You have to be certain the spark is disabled, as the disconnected spark plugs could ground to something and ignite the fuel in the air.

Overtightening shouldn't cause misfires (though it may make it nearly impossible to get them out without stripping the threads.) I'd check all your connections.
