Mine was changed at 72k about 4 months ago. I've been meaning to share these pics lol. Guess I can add on to this thread now. Mine look slightly better since I baby IS quite a bit more.

Comparisons between old and new. I'm sure you can tell which is which.
As for me, I could definitely tell the difference. Shifting and power seems way smoother and it felt like it restore a bit of power as well. I ordered from Sewell and did it myself following the DIY

*Images fixed.. and also added a close up shot.

Here's one of my with about 10k. The redish color denotes extensive use of fuel additives. :-)

Worked fine, was just curious to see what they looked like so I pull one and snapped a photo.

The old ones don't look too shotty hehe, but you always want those new spark plugs installed

I just bought some NGK ones as noted on this page

but I've yet to change them out. I was told by a friend that I needed to adjust the gap on all spark plugs, but I've never touched a spark plug til now.

They're Iridium, so supposedly they need no adjustment, or if they do, then conventional tools aren't supposed to be used, from what I read.

Thoughts?

No adjustment needed. They are set at the factory.

Trying to adjust the gap on Platinum or Iridium plugs you take the chance of breaking the electrode tip.

Just be careful and don't drop them.
