Changed my oil at 85K this weekend. Thought I would pull a spark plug and take a look. Looks OK. Surprising that this is the first time I have pulled a plug yet. Those new plugs sure are fancy and long lasting; as well as expensive. Took a gap reading. Looks to be at .045" with the factory gap at .043. after 85K the plug only wore 2 one thousandsth of an inch. How does it look to you guys. Was thinking about doing some engine maintenance this summer. Maybe I'll hold off. And do we run the "11" version of this plug? That is the "//" I see on the plug below the PLFR5A.

I take it that these are from factory installed. The electrodes look fine to me. I’m sure they will spark for another 10-20k without a problem.

I did mine at 105k in my 06 and they looked almost identical to yours.
