I just recently purchased a 2003 Excursion Limited 4x4 with 6.8 V10. It has 95 K miles and the previous owner said the plugs and coils were swapped 7k miles ago. I asked what type he swapped to but no reply. I tried Google searching the numbers on top of the plugs but couldn't find anything.

Does anyone recognize these?

 

Not sure which numbers used in your Google search but that's just a rather common COP found on a lot of Ford engines.

The COP's don't look as though they're only 7K miles old though---could the PO have meant plugs and boots were changed?

 

Standard ford part#: 1l2u-12a366-aa

Google that, and it comes up all over the place.

And JWA is right, that certainly doesn't look like a brand-new COP unless it's 10 years old

 

NOS sitting in someone's garage since '09 or earlier?

 

Thanks guys. That's what I thought too.
