Changing my spark plugs on my 1999 f150 4x4 5.4l
Any advice when changing them?
All help is appreciated

Thanks kyle.

 

Take your time, pop the fuel rail if needed, and torque to 28 ft/lbs no anti seize. A long spark plug socket and taping the extensions together will also help.

 

I use a spark plug socket with the swivel on top, 6 inch extension.

 

See I was told to use anti seize?

My instructions from a guy who did it on his truck (an 06) was this:

-use lots of penetrating spray
-get a special long socket from ford to prevent breaking the plugs
-only use ford plugs
And use anti seize when putting them back in.

Is this wrong and if so why??

Thanks again
Kyle

 

The 04-08 is a totally different animal. The 3v 5.4L had a problem with the plugs breaking, which warrants the need for anti seize. The 2v 97-03 5.4L has a problem with blowing plugs out of the head, which is why there is an updated 28 ft/lbs dry standard for our trucks. I do agree using Motorcraft plugs. SP479 would be the ones you want. For more info on plug breaking look here, especially FAQ #51.
