Wasn't planning on changing spark plugs today but...

...I already had everything off to clean the throttle body. I bought the truck new ('06) and have not changed the plugs or cleaned the throttle body. I already had the plugs so I thought why not.

I only have 39K miles on it and it is still like new. I could not tell a significant difference in performance other than it idled smoother. It never was extremely rough it just thought it should be smother so now it is.

Thanks to all who did the write-ups and contributed pictures. It was a piece of cake. I used anti-seize on the plug threads and my trusty torque wrench to 15 ft.pounds.
