Except that is for the old 4.6 modular motor, which I don't have. Not sure that's relevant for me...

As a professional Mercedes/BMW mechanic for 47 years, Not one plug that I put in, doesn't have anti seize on it. Too many problems seen with plugs getting stuck, or pulling out the threads, and on some of these cars, way too much work to get the Helicoil in. Use the anti seize!!

Therefore Ford wouldn't recommend using the nickel anti-seize, if there wasn't a good reason for it in the first place..
Nickel ! And the reason, the plugs have nickel plated shells/shields, not copper.. Also copper and nickel don't mix..

Yes, it is relevant.. The old 3v plugs have nickel plated shells, just as the 4v Coyote and yet Ford still recommended using Motorcraft high-temp nickel-anti seize on the ground electrode shields.. All that changed between the old 3v 4.6 plugs and the 4v Coyote plugs were the design.. Other than that, both are still made from the same material..

For the most part, the 3V had lots of potential and responded very well to mods.. However when compared with the design of the Coyote 4V, it falls way short in the PCV and spark plug categories..
What I didn't like about the 3V 4.6 was the dreaded 16mm high threaded 2 piece designed spark plugs that were known for breaking inside the head that required purchasing the Lisle extracting tool for removal which IMO is still a PITA..
I also wasn't thrilled with the 3V's PCV design that consisted of a baffled tube that was integrated into the cam cover and was non-removable.. IIRC if the metered valve inside the tube housing required replacement, according to Ford, they required having to replace the entire cam cover instead of just replacing a standard PCV valve like those on the previous 4.6 2V and 4V mod motors..
So from that point of view, I also couldn't make much sense as to what Ford was attempting to accomplish in the design dept lol.
That being said, at least Ford came back to their senses by re-designing the 3v heads along with going back to the traditional one piece 12mm spark plugs for the late 08-10 4.6 3v and also went back to the standard style PCV valve on the 11-current 5.0 4v Coyote..

Ford recommends 24ft lb torque for the 4.6 3v plugs !

So which engine do you prefer, the 3v or Coyote ? I see that you traded in your 07 3v for your current 14 which has the 5.0 Coyote.. Therefore in your opinion if the 3V is tougher and can take more tune abuse over the Coyote, then why not just upgrade to the re-designed 3v heads that use standard 12mm spark plugs that Ford came out with for the late 08-10 4.6 3V models

My 2006 mustang ran like a top until I put msd coils on it and then started stalling I did a top engine clean on it the car and it stop stalling but has not ran the same since I even put factory coils back on and still downtown run right when I pulled the plugs they were all carboned up and looked like they been through hell only have had 400 miles on them that why I put e3s in the car and it helped when I first started the car up and drove off but when I started going down the road car started going back to the same way I have never had a problem like this sound like a carbon issue I have no idea what is going on

engine and responds to mods well but it just seems more delicate than the 3v to me. No more 3v for me the Voodoo will be my next purchase.

Other than the plug design issues, I've been very pleased with both the reliability and performance from the 4.6 3v and don't have any other complaints..

Hey guys, Great info in this thread, plan on doing my plugs this weekend. Noticed most said nickel anti-seize and not copper. What I have at my house is this stuff. Will it work with a little dab on the spark plug? 2010 gt with 37k miles on it. Figured i do them now to get it out of the way.
It's aluminium anti-seize. Got it to use on lugs, and various other things. will this work for the spark plugs as well? Thank you in advance.

Aluminum anti seize is rated at 1400ish degrees F. Nickel anti seize is at 2500ish F.
My opinion is do not use anything else, get the Nickel stuff. You are, after all, literally playing with fire. Best to not mess with things for convenience sake... my thoughts.
