^^I agree^^ I think your dealer fibbed to you. Even the paint is faded on those plugs.

 

Can't dispute the receipt, but old inventory was likely used. They should have known better and used the standard design replacement.

 

Seeing what looks like mud on the wrench flats...I hope they shot those with air before pulling them out, so the grime wouldn't fall into the combustion chamber.

 

If those are the plugs they installed, they were not "new" when they were installed.

I don't think your dealer fibbed to you. IMO he bare face lied to you.


EDIT: Meant to ask if the truck runs better (correctly) with the plugs replaced. I'd also pull the new plug that replaced the severely deformed plug after a month or so and keep an eye on it.

 

After 30K miles the plug "might" have some discoloration where the insulator meets the base, but they sure wouldn't have that much gunk unless they have 30K miles over several years. There is no possible way that those are new plugs.

I have had plugs foul after 4500 miles, all four at the same time in a brand new Fusion Hybrid, but the outer body of the plugs were spotless!
