    Do I need to check all of them, or should they all be identical in wear and can just check 1?

    thanks

    As long as it runs decent, you can probably just check one.

    Not sure that is leaking combustion on the ceramic. The plugs have some kind of lube on the ceramic when installed. The color could be that lube that has been cooked. I was skeptical when I saw the Corporation saying the plugs are good for 100,000 miles. That has not been my experience with Irridium plugs. So, I checked mine at 71,000 miles and replaced them with NGK IX Irridiums, part # LFR5AIX-11 (4469), gapped at .047". I do not know what the OEM plugs started life gapped at. Nor do I know what was permissable quality control on them. The plugs I removed were for cylinders 1 through 4; .050" .050" .0495".050". May be #3 was dropped before installation, LOL. Pretty impressive, only .003" wear in 71,000 miles.

    I changed my plugs last week with 11,500 miles and the carbon build up was bad already; took some force but extreme care for the ceramic to get them out!

    I usually change my plugs every 20k miles, couldnt imagine keeping the same plugs for 100k.
