Now, I've never done the plugs in one of these engines...
But I just don't understand why everyone is scared to death of these things. I've read plenty of posts of people with both low miles, and 100K plus getting all plugs out intact....that being said, I've also heard from folks with low and high miles breaking plugs off, and having problems....
So, why is everyone so eager to fix something that's NOT broke on a new truck??? I have 19k on my truck...and it's possible for one to break if I change 'em now....or at 100K...but believe me, I would have an easier time justifying pulling the heads at 100K than 19K....
So I'm gonna wait, and tackle it when it needs it, and deal with it then...
71f100longbed...just how good is this tool? Using it, are you saying there is very little chance of dropping one into a cylinder?

There was a poll on here a few months ago that surveyed everyone that did it to see if they broke plugs, and if so how many miles on their trucks....virtually no one broke plugs when doing it under i believe it was 40,000 miles.....(there may have been one broke plug)....but the number drasticly went up as the mileage did....

Okay... I have a 06 with the 5.4. Tylus stated that they have the different plug. Now is that the one piece plug and is there a way to tell without removing the plug. This question may be dumb, but I am still new to this doing everything on my own, instead of just going back to the dealership.
04-05 PZT2F - Motorcraft Plugs - 2 piece
06+ PZT1F - Motorcraft Plugs (SP-462) - 2 piece
The PZT1F is a colder plug. Guess it's supposed to help combat the build-up of carbon vs. the hotter plug
supposedly the late 07 or late 08's have a different head design...but I still haven't seen any conclusive proof of this change. Just alot of people saying it's so.
Champion has a 1 piece plug...and I belive that Brisk does now as well

Hey...that was the post tylus.....thanks for finding that...I'll still stand by my opinion....virtually no one under 50K miles broke them, but hey...thats what the internet is all about...differing opinions coming to the same conclusion....the plugs still suck.....LOL

My dealer service advisor told me to do the plugs at 60K intervals, & they have not experienced any problems per the TSB........at this interval, I will let them tackle them when I'm at 60K or two more years of driving since I am at 30K now.....

Thanks for all the replies. That really clears it up for me lol. I think I'm going to hold off for now and take it in next year right before my 3/36 expires.

The Champion plug number is 7989. There was a thread in this forum very recently regarding some problems/potential problems. It is a one piece double platinum plug ($13.16 each at Rock Auto).
Brisk Racing does now have a one piece plug for stock 5.4 3-V engines - 3VR17YS ($18.99 each from Brisk Racing). These plugs are one piece but not double platinum (apparently). Brisk rates them to 50,000 miles but recommends periodic checking and regapping due to the 3V head design.
My 05 currently has ~23,000 miles and I will probably change them at around 30,000 miles with one of the above plugs. I think I will purchase the plugs and have the local dealer (fortunate to have a good one) change them, while doing subsequent plug changes myself.

FYI: engines with build date after 10/9/07 have the updated spark plugs. They are small like a four-wheeler plug and have brown coil boots.
