What plugs you guys run?

[jdan]

I've been servicing the 5.4L's for years and aways threw in motor craft plats and never had any issues from them. But I'm just curious if there is anything better.
I'm replacing my plugs this weekend.

Thanks in advance.

Everyone that has tried other plugs on the site havent had any luck with anything but Motorcraft!

I have wanted to try the E3's but dont want to throw money away!

Not true. I use NGK tr6's.
Most lightning guys use these but its wrong heat range for N.A. 5.4

I went with the factory equip. Autolights Irridium.. no trouble with plugs, intermittent trouble with COP as is common on these...

i stick with motorcraft for plugs/oil filter...highly recommended by a ford mechanic i knew in a few years ago...thats all we have in the air force...ford/chevy/dodge...he said when it comes to ford...stick with OEM for plugs and oil filter...anything else is fair game

 

[jdan]

That's what I figured with OEM.
I've aways liked using the same stuff they rolled out of the factory with.

Motorcraft it is!

Whatever you do, don't use Bosch. Ford + Bosch = problems.

I hate bosch plugs. Stopped using them at work because of misfires and other issues. Dunno why they still make them lol.

Alright I swapped in 7 motor crafts.
This took me about 40 minutes.. I'm use to removing a dog house on the vans to get to the back ones lol.
Reason I only did 7 is because I had a blow out awhile ago and it's been repaired with a new plug and sleeve so no need to mess with it.
Some of these where loose! I'm glad I got to it in time.
As you can see there is a Bosch. A Autolite. And the rest NGK's lol
Gonna swap in a new fuel filter and take it for a burn and see how it is.
