I was just looking on the Z board and it says the coppers are fine to run if you enjoy changing your plugs quite often. Most guys like the platinums for their typical longer life cycle.
But Andy’s car hates him so it is no surprise that when he worked on it alone without someone helping him that his car is now angered.
I don’t see whats the big deal…I don’t he drives enough each summer to do multiple plug changes…Run copper change the plugs once a year…1.99-2.99 a plug and a couple hours of your time for better performance?
Like I’ve said 100000000000000000000 times… just buy the NGK Coppers. 
i did the same things, had the same reaction. i run ngk coppers now and havent had a problem since. i dont trust a word anyone says on those z forums.

So i decided it was time to change the plugs, especially since i haven’t since the swap (a lot of miles ago). I had purchased Iridiums a while ago that members of NYSpeed discouraged me from using, but several Z board members said they’re great…
