Built in Norfolk. I don't know what plugs were in there originally. I can check the service report and see what they put back in, but I don't know if that helps much.

 

I have an 04 5.4 with a little over 12,400 miles on it. I plan on keeping it till at least 2008. Plugs have never been changed. If I pay for the cost of replacement before my warrenty runs out, will the dealer do it, or will they say they are supposed to last 100,000 miles? I would much rather have them changed out at least once before my warrenty runs out in case there are any problems, any advice??
