25k. at 16 dollars apiece this truck gets really expensive for a lousy spark plug change, but I guess that is cheaper than the things some of the dealerships have been doing for the change. I luvvvvvv my stinking Ford.

 

I could be wrong about the 25,000 but that is my recollection. I think because they are not platinum. Maybe someone else will chime in.

 

Platinum plugs are cheaper than $16. I think they're about $96 for a set for my 2002.

 

your plug is different than the 2004 plug. apples to oranges different.

 

I realize that but Ford's better idea sure exploded in their faces. I'd like to swap heads but not till something better comes out to fix this problem.

 

I've been putting anti-seize on my plugs since Ive owned the truck, I am getting ready to change my plugs for the 5th time, I have 132K on the clock and have never had problem with the 5.4 getting plugs in and out, I take my time and put very little torque on the plugs, just seat them with finger pressure and a little more, the only problem I have is i leave the stupid spark plug socket inside the spark pocket and that pisses me off when Im the back.

I use the silver anti-sieze and while it burns off i have yet to have a plug not loosen. I have Copper mud that I will be using this time though since I use the silver mud to deter theives from stealing my signs, that stuff goes everywhere. Copper seems to last upto 1800 degrees of direct heat

 

So this appears to be more of a 3V issue than a 2V issue. TRUE??????

I had 90,000 miles on my 2003 5.4 2V and oulled plugs with no problem. Then installed blower and NGK's for 35,000 with Permatex AntiSeize and 5 of the plugs came out easy, but three came out hard. Shoot WD40 in whole and used 1/2 in breaker bar and they came out.

 

Ford did not make the stupid two piece plugs. There are now one piece plugs that solve the breaking problem. Ford is responsible for the head design however that allows carbon build up in the plug threads.

 

Thats news to me. When did Ford start making a 1 piece plug for the 5.4L 3 valve?

 

When did Ford start making plugs????

 

Ford does not make plugs. Honeywell makes Motorcraft and Autolite plugs. All Motorcrafts and Autolites for the 3V are 2 piece. Brisk and Champion (Federal Mogul) make 1 piece plugs for the 3V.

 

Exactly!

 

Unfortunately, I highly doubt this will do any good at all...this is not a "safety" issue It is a very expensive design error on Ford.

 

depends on how you write it up, if you write that the engine failed while driving in the fast lane of the freeway and you almost caused a mutipile accident trying to get the heck out of the way, that could be a safety issue.

 

Just a note to all on the Kroil, I work at a chemical plant and we use PB Blaster (available at your local Advance auto) and it breaks everything loose we put it on.
So after seeing these threads and watching the video on these plugs, me and a buddy decided to put these oils to the test. We placed two 1/2" studs in the vise and wrenched down double nuts on each stud with the impact wrench as tight as we could get them leaving about 2 threads showing on top to create a cup (if you will) to place both oils in. Within 30 minutes the PB Blaster was running out the bottom of the nuts down the threads. By ther end of our 12 hr shift the Kroil still had not penatrated them.
We use a lot of acids here and every nut and bolt gets eat up and corroded bad in a very short time frame and I can swear by this product, when it comes to breaking rusted bolts or anything else loose with it.
Try it some time, it works. Cost about $6.00 where I am. My 5.4 is at 36k right now so I am looking to change mine very shortly and PB is going to be put to the test on it. I will be commenting here when the time comes.
