i'm planning on doing my plugs at 30k. ive got an 07 and i want to do them super early so i can get the updated plugs in ASAP.
do you guys go to ford for updated replacement plugs or use another brand?

 

I guess Champion makes a replacement plug, though I have heard that they have issues with that plug.

Pretty much, if you get the OEM plugs at Ford, Napa or whatever, just put the anti-sieze on as the TSB recommends and it shouldnt be a problem in the future.

 

i guess i'll just ask the guys at the Ford parts counter for whatever they recommend.

i thought the problem was that the old plugs were 2 piece and that updated ones were 1 piece to avoid coming apart.

 

No, the heads were redisigned in early 2008 to go toa one piece plug. The Motorcraft for your truck is a two piece. The only one piece in the correct heat range is made by Champion.

 

The correct heat range for a supercharged application is not the stock plug heat range, but a range or two colder. Brisk makes a colder range plug that is one piece, but it's not a long range plug. You have to change it every 20,000 miles or so.

 

I do the same with Autollite/Motorcraft HT0s so they come out with no problems. They work great gapped to 32-35, cost less than Brisk and don't erode away in 20,000 miles.

 

I'm sure some one will come along with a long life colder plug for the new style heads, if they haven't already. That was my only option at the time of my install. But even at 20,000 miles that's almost a couple of years for me.
