Have 03 edge 3.0, 46k, what are the best plugs and best wires, is 100% factory except for mobil 1, has auto and gets 17 to 18 mpg, thank you to all & merry christmas

 

Just don't get Bosch or Splitfire.

 

I've never heard a bad thing about Motorcraft plugs

 

motorcraft or autolites will be your best bet. ive heard good and bad about other brands but these two are pretty consistent.

 

I'm getting denso irdium plugs with Bosch wires

 

I'm running NGK Iridium plugs in 2 of my vehicles and love them.

 

I run the Copper NGK plugs in my 3.0L. I replace them ever 8,000miles or so. In my opinion, you won't gain anything by the fancy/expensive plugs, other than the fact the service interval is longer. I don't mind changing plugs, so I run the coppers.

I used to run Autolite, but they went from America to China. So atleast I'll run a GOOD from Japan. Than a half-*** one from China.

 

I've been using NGK wires and NGK Iridium IX plugs lately, on other vehicles, and really like them - your truck takes NGK 52014 wires and NGK 7397 plugs...I think.

 

Motorcraft or Autolite only thing i have ever used

 

If your gonna stay stock the motorcraft plugs are a good value.

Check out the spark plug area on my web page.

Stay with the Motorcrafts, either double platinum, or finewire platinums.
