ps. Good luck finding any of these plugs here. I asked if they can be specially ordered and their responses were "they don't even come up with a part number on file, how can we order them?"
I know, I'd already experienced from PartSource saying the only Iridium they can order is the ZFR6FIX-11 (which I'd brought), but then I found out I actually need the 7 heat range...
that's why I want to find out where I can buy them....
