Anyone us the double platinum plugs? If so good or bad

 

If for s 5.4 Motorcraft sp515

If for a 4.6 Motorcraft, ngk, Denso.....

Champions don't have a good life span in these picky motors.....

 

not very good, I had one fail after roughly 15k. Stick with Motorcraft.

 

I have tried the E3s and the Champions in my 07, all failures after a few thousand miles, have gone back to the MC SP 515s and will stay there unless MC does come out with a one piece plug. The Triton motors are VERY picky on most items, plugs in particular.

 

Thanks guys....wish someone in Columbus Ohio area could tackle this for me.

 

I switched to champions at 100k miles on the truck (5.4L). 25k miles on the Champions and no problems! The reason they fail is people don't change out the COPs at the same time.

 

Guys question I just went to advanced auto part web site and auto zone typed in the part number for motorcraft sp515 and it said that they don't fit a 07 5.4 flex fuel motor?

 

Why would you have to change the COP's? Would the MC's also fail if their COP's weren't changed? I just don't understand that.

 

same plugs......https://www.f150online.com/forums/4553636-post17.html

 

I am in Kentucky just South of Louisville if you want to make the drive.

 

I switched to Champions 28,000 miles ago and so far absolutely no problems!
