Ford # PZH14F or motorcraft SP-515

Also be prepared to break at least one of them during removal. The worst one I did all 8 broke, but have had none break too.

4play,

I've heard that broken plugs is a problem in that vintage of trucks. So, how do you get the broken plug out of the head?

Next time you need to look up auto parts, check out the Rock Auto website.

They are a good outfit to buy from, even if not buying from them, the part numbers are shown.

They make an extraction tool/kit for getting them out. Some of them are a little different than others. Also the plugs break in different ways, meaning how much of the plug gets broken and/or stuck in the head. The best case scenario would be just having the metal sleeve stuck but the porcelain and electrode could break and too. Either way the tool is made to extract the broken piece and I am sure your local auto parts store has them for sale, loan/rent.

Broken plugs suck, especially multiple plugs or the back cylinders but I have done so many it doesn't really bother me anymore.

4play,

Thanks for that response. My son has a 1999 F-250 with a V-10 engine. It's been a LONG time since the plugs were changed. I was thinking about doing it, but at this point, I'm thinking that I'd be better off having someone do it who has some experience with these things.

Thanks again,

If I had one of the "plug problem" engines, I wouldn't even think of changing the plugs unless it had a serious/just about won't run problem.

2-valve 4.6 L, 5.4 L, and 6.8 L engines found in many 1997–2008 Ford, Lincoln, and Mercury vehicles have an issue with stripped or missing spark plug threads in the cylinder heads. Ford acknowledges this issue in TSB 07-21-2 as well as earlier TSBs. Ford's TSB does not state that this issue is caused by owner neglect. Ford's only authorized repair procedure for out-of-warranty vehicles is to use the LOCK-N-STITCH aluminum insert and tool kit. For vehicles under the New Vehicle Limited Warranty, Ford will only cover the replacement of the entire cylinder head; however, the Ford recommended spark plug service interval extends beyond the duration of the New Vehicle Limited Warranty.[57]

3-valve 5.4 L and 6.8 L engines built before 10/9/07 and 3-valve 4.6 Ls built before 11/30/07 found in many 2004–2008 Ford, Lincoln, and Mercury vehicles have an issue with difficult to remove spark plugs which can cause part of the spark plug to become seized in the cylinder head. The source of the problem is a unique plug design that is made with a 2-piece shell, which often separates, leaving the lower portion of the spark plug stuck deep in the engine. Ford acknowledges this issue in TSB 08-7-6 as well as earlier TSBs. Ford's TSB does not state that this issue is caused by owner neglect. The TSB provides a special procedure for spark plug removal on these engines. For situations where the spark plug has broken in the head, Ford distributes multiple special tools for removing the seized portion of the plug. The multiple procedures required for the different cases/situations of plugs seized in these engines are explained in the TSB. This repair is covered for vehicles under warranty; however, the Ford recommended spark plug service interval extends beyond the duration of the New Vehicle Limited Warranty.[58]

Federal-Mogul, parent company of Champion Spark Plug, and Brisk Silver Racing have introduced a 1-piece machined shell 3-valve spark plugs that addresses the OEM 2-piece spark plug's separation issues.[59][60]

check with Napa ,they carry the tool for removing the plug if you break one.

Good Grief! Thanks for that additional information JMOR. My son's truck runs okay (for a truck with 275,000 miles on it), so I'm not going to do anything about the plugs.

When the ol' gal quits, it'll be past time for a replacement truck anyway.

Thanks to both of you guys for the great information.

Ford/Motorcraft also came out with a one piece plug
