right now i have 15,000 miles. has been tracked a couple times at most. I probably need to change them, but is there anything else I need to change along with the plugs??? And secondly I think I saw a past post that recommended the stock plugs over aftermarket. Just checking. thanks for all the help guys.
Re: how often should I change spark plugs? (Nameless)
if your putting sand paper to the spark plug you might be sanding off the platnim finish... and also making the gap bigger...
Just use chemicals or buy new- for .99 I buy Champion RC12MC4 they last 7-10k miles and work good.

Does anyone know the benefits of using copper plugs? Any?
I remember reading a loong time ago that copper plugs perform better (in what way, i cant remember) but dont last nearly as long as platinum tipped plugs.

stock plugs is all i use.. - with stock ecu its easy to run healthy to 40K miles, but good idea to have them checked at least every 30K... with aftermarket ecu/ignition/changed timing - its a good idea to cut it down to 10-15K..
also check dist. rotor - make sure its not fried or anything.. -
