Old.plugs actually looked really good....all the same temp, bo oil deposits, etc. I didn't expect anything different but nice to see. Surprisingly, not a single.coil pack had a single crack in it and believe both these plugs and coils are original to the car as no writing on the black end of the coil and I've owned the car since 28k miles so before plugs would have have been due at 30k (which I didn't do until now).
