Since no one has posted pics of plugs with 60k on them I figured you can see how they held up.
they look warn but ok. Denso looks less worn.
I think they do 3 & 3 so if you show up with a blown engine @ 50k and the stealership sees the 3 & 3 plugs they will know they are original and void your warranty. just my theory.

did u replaced them with the same brand plugs and 3 of each? How about a write up on how to change them plugs? for us newbies.

I got 6 Denso.
It can be a uncomfortable squeeze for larger hands on the driver side.
The pain (on the driver side) is disconnecting the wires from the individual coil packs.

be sure to get a 10" extension for your wrench plus you might use your 2" extension on the end of that one.

One helpful note is inside the spark plug socket is the rubber boot... to cut some rubber off... so it is shorter. This will keep the socket from disconnecting from the extension.

Dang, those look good. Mine at 60k were worn down hard. See if I can get some pics of them. It was weird that half of them were denso and the other NGK. I put all NGK in for the replacements.

Here is a link I started over 2 years ago about the 3 Plugs on one side and 3 on the other.

Do a search for "NGK Denso" and you will come up with 3 pages of threads.
