Looking @ replacing my spark plugs, what are the best plugs to use?

I assume I need anti-seize
have heard rumors of them becoming loose, and blowing out, thus destroying the threads in the head?

what motor do I have? have been seeing 5.4L 2V, 3V, or 4V?


My truck is a 2001, F150, 4x4, XLT, Supercab, 5.4L motor (L code), 4R70W trans.

Looking to order these TODAY
TIA!


EDIT: just found this thread, lol

trying to confirm a few things right now, then off to amazon


what about the best tools to use for the job? anything work better than another method?

 

Use Motorcraft spark plugs. The common advice is to not use anti-seize and torque the plugs to 28 ft. lbs. However, when I replaced my plugs I did use anti-seize on the threads. This was 30k miles ago. I bought my plugs from Advance Auto Parts for less than $3 apiece. They are a pita to replace. Just take your time and you can do it. I did have to pull the fuel rail on the driver's side to get to one plug. I did not need a universal joint or socket that had a universal built in.

 

from what I am reading, this is what I need?

2001 through 2003 Motorcraft ASWF-22 or equivalent @ 0.045 inch

 

Motorcraft SP479, NO antiseize, torque to 28 ft/lb.

Www.blownoutsparkplug.com FAQ 51 and 52.

 

Those are for sure the right plugs? Not the ones that are specified by my manual?
2001 5.4L gas

also, what Gap?


the SP-479 is a AGSF22WM

that blown out sparkplug link isn't working for me

 

Q: Why do you prefer 28 foot lbs torque instead of the factory specification?
A: Over the past few years we have heard from many of our customers that they tightened their plugs to the correct torque but they still came loose. We worked with 10 other Ford Certified Master Mechanics and concluded that 28 foot lbs of torque would be satisfactory. We have been using 28 foot lbs of torque for many years and have never had one come loose or strip out. To verify that we would not damage the original threads we used a test cylinder head with good factory threads we applied over 100 foot lbs of torque to the spark plug without any failure.

Q: Do you use Anti-Seize when you install new spark plugs?
A: No, we always use Motorcraft nickel plated spark plugs to stop any issues with electrolysis.

YES, I'm POSITIVE that's the right part number or I wouldn't have posted it. Sometime in the past 17 years, Motorcraft changed all those "A" part numbers to "SP" numbers. Gap .054.

Ordered this:

 

Also some dielectric grease

 

The Denso boots and springs are a good choice.

 

good to hear.... I know Denso is OEM on a lot of vehicles.
