Pictures of old spark plugs

As you may have gathered from previous posts, I replaced all 6 spark plugs this weekend. I had an issue removing from cyl 5 and had to buy a longer extension, but I finished the job a couple hours ago. I swapped the 4 and 5 coils just in case the misfire comes back. But I took it out with the Cobb Stage 2+FMIC Sport reinstalled, hit 4k a couple times (hard to redline around here with Stage 2), and it felt really smooth. It felt like the delivery was a lot more consistent and predictable, especially down low. No codes after a 15 minute drive, but I'll continue to monitor it.

The main point was to share my pics of the old plugs:
