been there done that, used to run through them all the time, turns out my tuning was causing some of it and also a header leak on the drivers side. Bosch for whatever reasons didn't seem to last more than a couple months, so I bought them from Orielly, 1yr warranty and changed them like underwear as needed.

I'd start with your tuning 1st, they shouldn't really give you problems unless something else is going on, burning to rich, etc, etc.
