My apologies OP but now you have been warned lol. Get some motorcraft plugs or NGKs. You can always wait till the autolites fail if you really want to but your engine will thank you the sooner you get some good plugs in there.

I hope he has better luck with them than most people do with them.

Well this forum is where I read either motorcraft or Autolite double platinum was the way to go. Ngk double plat was second choice. Hey if I gotta spend another hour changing the plugs out again it won’t be any skin off my nose. Besides 44 bucks felt a lot better to spend than 100 bucks. Also the plugs I bought have a 5 yr warranty so I guess if they fail it’ll be on them.

On a further note, my CEL indicator apparently does not work. When you turn the key to the on position before you start the truck there is no light. No service engine soon, no engine icon no nothing. Took to advance auto and their ob2 machine couldn’t read my vehicles codes because it wasn’t a 2000 or later.

Order the plugs from Amazon. You can get all 8 Motorcrafts for 30 bucks. As far as Advance, any OBD-II reader should be able to read it. It is 96 and newer that has it, not 2000 and newer. Another parts jockey with their head up their you-know-what. Could you point us to where you read that info on the recommendation for Autolites? I'd like to go straighten that out.
Here's a link to where I get my plugs:
