Plug Condition after change

[AE1M]

The thing I like most about this vehicle (08 6cyl Limited) is the ease of doing all the owner capable service. I put Iridium plugs in after 30K miles, and decided to replace them now at about 120K. Nice 30-45 minute job and look at how these things look after 90K miles. I am amazed.

Pretty damn clean in my opinion.

When I pulled mine I realized they were the original plugs--with 184,000 miles on them. The electrodes looked slightly more "worn" than those but they were still doing the job. Denso is a damn good spark plug.
