My 08 5.4L has the revised plugs and brown plug boots. Fast approaching 100K miles, so I'm getting everything together for the plug change, among other things. Looking at RockAuto, there are lots of replacement options, but I'm probably going to go with Motorcraft...unless someone has a compelling reason to choose another. I see that there are boots with springs, and without. The motorcraft replacement boot does not mention the spring at all (included, or not included). So....
Do Motorcraft 8l3z12a402a plug boots come with a new spring?
If not, what is the part number for the spring?
Does Ford make boot kit with 8 boots and 8 springs?
Thanks!

 

I just went through this with my 06 5.4. Motorcraft boots do not come with springs unless you buy motorcraft coils and to my knowledge, you can not buy motorcraft springs separately. Pretty ridiculous in my opinion.

 

^^ Had that set in my truck since October 2013. Not a single problem, even with multiple removals and reinstallation to fix other problems. Highly recommended... can't beat a whole set of 8 (including springs and boots) for the price of one MC.

 

They say they won't fit your truck but they also say they wouldn't fit mine and clearly that's false... here's another set.

 

Only hiccup there is that the set you linked doesn't work with the 08s with the revised plugs/boot. That is a good deal, as long as the COPS continue to perform. My COPS are fine, so I was hoping to just get Motorcraft (or equal or better quality) boots and springs. Thanks all the same.

 

ACDELCO 16075 {#88865134} Professional
Single Pack; w/ Brown Coil Boots
$2.33

This is what I installed...look/fit/function just like the OEM ones I replaced...comes with springs.. use a little dielectric grease inside the boot at each end to seal out moisture...SP-509 plugs were a good price @rockauto also...

 

I just did my plugs at 78,000 miles due to a misfire on #5. (2004 4.6)
When I pulled the COP, it was sandy and damp. All eight were sandy and damp. Still in good condition - pliable, no swelling or cracks, springs tight and bright.
I just cleaned them - dried them and reinstalled with dielectric grease at both ends.
So far so good.

 

I was hoping someone had experience with another brand. I think I'll go this route. AC Delco has pretty good rep, correct?
On a related note, isn't AC Delco affiliated with GM like Motorcraft is to Ford?

 

They are very good quality whoever makes them...they were completely like the OEM one's I removed... clone's

 

That's why I posted the second one...
