Now, and this seems as much a debate as anything, which plug? Single or dual? Not really clear on the "grounded" part of the other discussion, but don't think that comes into play here.

I can point you to quite a few threads where people running Bosch plugs on these motors have had issues, both with performance and MPG problems (there have been others claiming that they've been fine running them despite the waste spark issue). I think Brian outlined the issue pretty well.

Back when before people knew better, you'd see alot of posts like this:

You certainly won't see people recommending them anymore, but it's your truck, run what ever you want, but most will tell you the potential hassle isn't worth it.
