I've been working on my daughter's 08 GP, and it's the first time I've had to use iridium spark plugs. I bought a set of AC Delco 41-100's, and didn't notice I'd gotten 100's instead of 101's, which is what it needs. Well, I always check the gap first, and the 100's are gapped at something like 035-040. So I was glad I checked them, and proceeded to open the gap to the required .060, and the needle thin wire electrode snapped off, leaving the larger section of the electrode. When I started researching iridium plugs, though, the pics I'm seeing have an electrode the size of "what's left" on the one I gapped, and don't show a needle size extension sticking out from the other electrode. My question is, would this plug still be usable without that hair fine section that is now missing? (FWIW, I bought a set of the 41-101's, which were gapped correctly at .059 - .060 and installed them instead) I just want to know if the two broken ones I have (didn't notice I'd snapped the first one till I saw I'd broken the second one, too) I'd like to give these to someone who could use them since I've don't need them now. 4 are still untouched with original factory gap, but if they still fire without the hair thin section at the top, maybe someone could still use all 6. I hate to just throw $40 away. Thanks, Lee
