Well, they would be hotter 
. I' assuming they would draw more powere also. Already in short supply if your running a factory alternator. I think the factory plugs get plenty hot to fire the diesel fuel and work just fine. Also, be aware the mid year 04 model engine changes included different legnth glow plug. Be sure to get the p/n right.

Installing Wellman GPs
I'm in the process of installing Wellman GPs. No GP codes, just one of those prevent maintenance things I tend to do. Literature says they get hotter quicker then OEM and from my GP lite the on time appears to be a little shorter on normal cold starts. Noticeable shorter on hot starts. Seams to start as quick if not quicker and does not run as rough as it did on real cold starts. I only have the drivers side installed. Too damn cold to do the other side. No problem removing or installing. A magnet works great to remove them. Torque is 168 inch pounds or 14 foot pounds.
Also, before I did the driver's side, I sprayed Liquid Wrench rusted nut loosener stuff on the connectors, the night before, to reduce the possibility of breaking the connectors. Connectors popped right off. Used dielectric grease on the O rings when I re-installed. Connectors popped right on. I have 122K on the X and have never replaced the GP connectors.
OEM GPs looked fine. Normal distortion on the first 1/2" to 3/4" of the tips. No tips were cracked.

Coming up from the old 6.9 idi diesel I know better. It's Motorcraft or nothing. All the other brands had issues with failing and having the tips expand. Once that happen and it failed, upon removal it would get stuck and break off inside. Some guys ending up pulling the head to get the broken piece out. Some that were unaware and ran it destroyed pistons.
OEM or nothing for me. They work just fine.
