These are 3 of my 6 plugs out of the G35. They are supposed to be 100K iridium plugs. This is after about 40K. All 6 look about the same. I am pretty sure they would not make it to 100K. This is my fourth set of plugs in this car.
They are one heat range cooler than stock, but otherwise the same plug.
I put a new plug in one picture so you could see the electrode wear. Being iridium, these can't be gapped.
