OK? They were ship in USA. The plugs I pictured were 41-110 12621258. The plugs you mentioned were 41-110. 12680072 (which I noticed has a “Z” on the tip). So is one plug platinum, the other iridium? I have both plugs, which is which? Which should I use? Thanx
ok, the plugs I just removed from 2000 z51 hatchback are: 41-952. 25321615.
what I’m hoping to replace them with 41-110. 12621258. Are these the right plugs and what were the old plugs???
pictured is passenger side The first plug cylinder # 2(?) electrode is darkened unlike the rest?

Interesting how the #2 plug (?) is darker. Perhaps a slightly leaky injector in that cylinder?

here’s the old line-up. I think these were original set ( inspection dots still on) can it be known by plug # ? Haven’t seen those # thrown around for replacements.
