Wow. There is no way I would change my spark plugs twice a year. Maybe if they were easy access but considering it takes an hour to replace the #8 plug (and you have to be underneath the car) I would have to pass on the semi annual plug change.
What I want to know is why you would need to? I have always heard (until this thread) that plugs last 100K miles these days. I bought my car with 45K miles and replaced the plugs and wires at 70K. And I thought that was overkill. I wasn't planning another change until at least 110K on my clock.

And I get ancy pretty easy, I always have to be doing something to my car or be planning on something. So spark plugs once a year helps w/ my problem

It's true, plugs on modern engines do usually last a long time, however I do notice a slight difference once my plugs get some miles on them, so that's why I like to have fresh plugs in there so much. Besides, a plug change on my C5 only takes me 45min, not even rushing, it's super easy. Actually, even when I had my 98 Formula I could do it's plugs in 45min too. I've got skinny arms though, so plug #8 wasn't too difficult for me to reach from up top.
