my rebuild has about 15k on it now and this is the 3rd set of plugs that i've put in so there werent that many miles on them.

i think my problem was bad cables caused the plugs to die so fast.

Why would that cause plugs to go bad?

not a strong enough spark to ignite all the fuel leading to build-up on the plug faces

in other news, my new rims finally came in. i can't tell you how hard it was to get these in the proper offset...

I need to get a compression test done on my car, just for some piece of mind.

additives in your fuel(not premix but additives like fuel injector cleaners)
ignition boxes like twin power and MSD overwork the plugs and wear them out faster
weak grounding can also cause the plugs to wear quicker

News flash: we don't have to answer any of your questions.

And starting your question with 'WTF' usually means I'll ignore it.

lol, good one... I was about to say the same but it's much better coming from a vet such as yourself. :-)

I guess reading comprehension isn't one of your strengths. He is my QUESTION.

you still need to show some patience when asking a question versus getting all pissy like a bitch after a few hours.

I guess it's not mine either because I thought what he wrote.

Since you've alienated/pissed-off someone who could have answered your "why" question with authority, you'll have to settle for my opinon (FWIW)....
Karack mentioned earlier that ignition amplifiers will wear-out plugs quicker. I've never run one, but guessing that's the biggest reason for erroded electrodes.
Also, by design the combustion chamber of the rotary exposes plugs to the heat of the combustion event for a longer time period than a piston engine. Particularly the leading plugs and with forced-induction. So getting the right heat-range is more important. Too cold and they foul quickly, especially since one way or another there's oil being injected in with gas. Too hot and you risk detonation. Regardless, even with proper heat-ranges that oil will tend to carbon up over time. So we should be changing them more often.

No, but issuing a temp ban is one of my strengths

I was trying to take it easy on you b/c I lived in Oki when I was younger, but you just earned yourself a short vacation chief. I suggest you take the time to research and learn a little and maybe you'll be able to answer your own rudimentary questions

Also, if you have bad wires, and your spark is arcing, then I think that raises the voltage and fries the plugs.
