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:

Car only had 39k, only 8k are mine. No idea when or if they were replaced before. Plugs are in no particular order, I forgot to mark them.

Well it is an 07, but it had low miles to begin with and I don't drive to work. It had a JB4 for most of the 8k miles, mostly on Map 1 then Map 2 towards the end. I've only had the Cobb for a few hundred miles.

No comment I do appreciate the benefit of removing the extra hardware, and the ease of logging without having to pull out my laptop. That being said, I need to get back to the dyno and drag strip once I ensure everything is running okay to make a true comparison.

Mine looked the same after ~35k miles. No oil residue or anything.

I would hope so, at least on Aggressive if I mix with 100 octane. It would be nice to see if it's running okay on Sport and see what it does with that map as well, since that will always be my DD map.

Took it out for a nice drive today, finally. Seems to be running much better, no misfires on Sport map. Since I was getting them even on the stock map, just getting on the expressway, I'd say this solved the problem. I did a lot of pulls, including one from 30-75 onto the expressway, and it never threw a code. Still seems to be adjusting after switching maps, but it seemed to be pretty much dialed in at the end of the drive.

My oil temp stayed between 228-232 the whole drive, water was around 200-202. And maybe it's a placebo, but I popped the hood at home and overall the engine seemed much cooler. Wouldn't be too surprised since it's probably running more efficiently.
