These plugs had been in the car for approximately 400 miles. I pulled them and noticed 5, 7, and 2 seemed to have a lot darker base ring than the others. In fact 1, 3, and 4 almost looked lean by comparison. Rather odd.
So I put a fresh set of plugs in and ran for about 80 miles. Getting pics to show up the way the eye sees them is not always easy especially with a cell phone camera so here's a pic under the LED shop lights.
Then the next two are outside in natural sunlight.
Notice the dark base on 5 and 7. 2 not looking near as bad as the first set I pulled out. 3, 4, and 8 look practically brand new.
What do you guys make of this? I'm not having any issues, just something curious I noticed. This is on E85 and was a mix of "normal" driving and some WOT running.
