lamp, 
I don't know if these are the original plugs or not but if they are then they have 201k miles on them.
None of the insulators are broken, unlike on gen 3 the original broke insulators and caused DTCs at 150k.
But I changed them cause I noticed some misfiring and nobody knows when they were changed.
The tips look a bit eroded so maybe the new ones with the pointy tip will help.
