I use Autolite coppers and change them every other oil change. When I did a PI swap onto my npi block I went one stage colder. Now I have a full pi engine and use the stock temp plug.

Thier is a search for box on the top right of the page this has been answered.. when you have a real question like witch CAI to get.. or what gears should i run.... or how do i do a 4v head swap... or whats the biggest tires i can fit on my car then start a tread and ask... hope i dont sound rude but the search for box is thier because it was supose to be used.

Stick with the Motorcraft it calls for, some of the "extra" plugs mess with idle quality, etc., unless you have a extremely changed engine combo and the builder calls for different.

Every Ford tech out there including the ones that created our cars have said to stick with motorcraft spark plugs. But if you can point me in the direction of a link that would change my mind I can always learn something new. And when has anyone heard of motorcraft spark plugs having problems?

Every Ford tech may say stick with Motorcraft, but the y are biased. Platinum sucks in a preformance application, as do gimmick plugs like mutli conductors, etc. Use copper conductor SP505 motorcraft plugs or the equivalent. In my opinion KGK makes the best quality plugs, but I usually run the SP505's, they work very well.

Absolutely no problems using Motorcraft plugs matt, just not the platinum version, they run hot and are more prone to backout, their only advantage is longevity, that's why Ford uses them.
The copper core Motorcrafts are Fine and you can still get 15-20K miles out of em
