Yup, never changed the plugs until yesterday on the 04 and here's what they look like.

From left to right is number 8, 6, 4, 2 plugs or back to front on the passenger side of the engine.




From left to right is number 7, 5, 3, 1 or back to front on the drivers side of the engine.





Other then the gap being wide on 3 of the 8 plugs they look pretty good and should help you sleep better knowing that 100,000 miles is O.K. especially when you consider they cost almost $10 a pop.

On a new plug, is the center electrode cylindrical in shape or does it look like a cone; as the old ones do? All the plugs in the photos look like the chinese conical straw hats to me.

They are cone shaped and already pre gapped to .043. The Service manual says that if you remove them for inspection it's okay to clean them but not to regap them.


My how times have changed.............

Wow. They look really good for 146k. You put the OEM NGK's back in?

You bet OEM. I'm getting the truck ready to be given to a friend of the Queen so the Queen can take posession of a 2011 Pro 4X.

Next is serpentine belt and check/replace brake pads as needed.
