how many miles? i just did mine today at 7500 w/ seafoam and they actually looked similar or a bit worse.

the denso itv22s feel smooth on my butt dyno. glad i did it.

useless trivia - didn't know denso made the stock tmic.

Mine looked exactly like that, 21000 miles, just did them thursday. Its been said a few times on here that the stock plugs look real bad when they are changed.

And yes, I was surprised to that Denso makes our TMIC! Wonder what other surprises like that are inside our engine bay?!

Kinda where I was going was to elicit comment on the large difference in mixture that was being burned. to really read a plug you need to see the porcelain up near the base, but other things being equal you can check cylinder variations looking at the tip. As you can see from my pic, 2 is much leaner than 3
