Rock Auto has several brands of COP boots.
Black boots = 2 piece plugs = SP515
Brown boots = 1 piece plugs = SP509
Have your buddy do the plugs and boots and go from there.

Well I went with the plugs only. Sp515, got them locally for 12 bucks each, 103 for all 8. The guy who did it charged me 170 to change them. Only 1 broke, #8. I figured if it keeps acting up I can swap the coils on my own.

Motorcraft does not have a one piece plug for the 5.4l 3v. If replaced as per the TSB with the nickle anti-sieze on the shank, and replace them at 60,000 miles interval, you should be in good shape. If you are dead set against the two piece plug then, of the 3 brands available (Champion, Brisk, E3) then the Champion would be my choice, some members are having good luck with them. That being said, I believe driving habits, fuel brand and type contribute to the success of the Champions...give them a try, then you will know.

I just installed these off of Amazon and they work great. Truck purring like a kitten. I am pretty sure these are from the eBay seller uneek that everybody says is good to go.

Installed COPS yesterday. My buddy (owns shop) can't believe 8 COPS were $75 total...and I can't either!!
The COPS even include boots/wires. It's only been a day, but it is running great!
Amazon seller shipped same day Priority Mail, and I had them from CA to OH in two days. Pretty hard to beat! I will report back if problems arise.
This site is an amazing asset. Thanks to all!
