I put a set of Motorcraft plugs in her and never looked back since.....2 years ago that was.

the problem is that I have seen several different part numbers on bosch plugs that look the same for the solid state controller application.
Bosch makes a duratherm plug for the 6.2-6.5, and I have used them with good results.
Well, that's because it's a Duraterm plug. That's basically the first constant duty glow plug made. Those things were designed for the EU emissions standards on the new high tech diesels and in cold weather the computers will sometimes keep the things burning all the time to keep tailpipe emissions clean. It's just about impossible to burn out a duraterm on a running engine... problem is, Bosch doesn't make one for our application, I''ve contacted them personally and they have no plans of making one either because it's a limited application plug so the only bosch plug that oficially fits our engines is an old style plug. Now if someone had a huge stock of duraterms and had the time to match up a set that could work in these things, I would imagine they would work great, but the plugs that Bosch has listed for the 7.3 just plain sucks and doesn't hold up
