Successful Spark Plug Change!
Successful Spark Plug Change!
Tonight after work, I set out on the task of changing all of my plugs. I went with the Autolite's HT1's... My truck has about 36,000 miles on it. I know it's pretty early to change the plugs, but I wanted to be safe than sorry...


Sorry for the lousy cell phone pics... Every single one of them came out unexpectedly easy. No issues at all. No screeching, no binding, no probs at all!
Even though I bought a can of PB Blaster, I didn't need it... ... ... However, I'm not real pleased with how they look after only 36,000 miles. They were the PZT-2F's. Again, I replaced them with the Autolite HT1's. Just based on my initial test drive of 10 minutes, it seems to idle much smoother. Before the plug change, the idle was shaky. But now it appears to be smooth as silk. But only time will tell if it's real or just my imagination.... Anyway, one less thing to worry about now. I coated the new plugs with anti-seize, so they should be ok next time around too.
Oh yeah, total time it took was about 1 hour and 20 minutes. Not too bad considering all the stuff that I removed (PCM, PCM bracket, air intake tube, air filter box).
Oh yeah again
There was one 1F plug, and seven 2F plugs... Last month when I had a misfire problem, the dealership replaced the plug in cylinder #4. They went with the latest recommended plug (1F), but didn't bother to swap out the others to match! What dipsticks!

Does Bosch make plugs for the 5.4?

And it's my understanding that it will be this way for a long time to come, as Motorcraft and Autolite have the patents on these plugs.

Ah, why?? I used "Permatex Anti-Seize Lubricant"... I didn't notice if it's nickel or cooper... What if it's cooper? Am I in deep do-do??

Thanks, but now I'm REALLY worried about what Adam06FX4 said about using nickel anti-seize instead of the cooper stuff... I PM'd Quintin asking for his thoughts; hopefully he'll respond soon so I can (hopefully) put my mind at ease!!!

The copper anti seize doesn't have as high a working point, it's only good to 1600°. The nickel anti seize is good to 2400°. It gets hot in their that's the reason for the nickel anti seize.
Looking at the 2 plugs that are darker the first thing that came to mind is the dreaded injectors sticking that 2005's had or are you using any oil?
Anyway it's good to hear a success story, but that's should be expected with that low of miles.
