I've just purchased my 2000 f150 and was looking to change the plugs and wires. Currently it has bosch plugs, but i was wondering what everyone else was using b4 I made a purchase. My plan was to go with the factory replacements. Like to hear your opinions and stories. Thanks

 

I'm going to try Denso Iridiums from Troyer.

 

i always use oem. they have worked well for me. a little expensive but the double platinum motorcraft plugs do well

 

Something to remeber. Unless you have modifcations to this engine Autolite/Motorcraft double platinums are the way to go. The Denso's are great if you have mods and are wanting to make a lot of HP. But for a stock motor stick with either Autolite or Motorcraft. I have Autolite double platinums in mine as we speak...gained 40 miles per tank.

Use motorcraft sprk plug AGSF-34F-MF4. This is the finewire plug that replaces the orginal plug. Ford has updated the majority of their plugs to this finewire design because the platinum in the finewire design lasts longer than the original platinum design plugs.
