A while ago, the discussion was brought up about that we should get AC Delco platinums. I have Bosche platinum 2's in mine. If I switch to The other ones, what differences will it make?

This has been discussed almost to death in the forum. Try running a search on Delco Plats and you will find A LOT of info about it.
Basically, the design of the Bosch plugs - or autolite, champion, etc... - is not conducive to good engine performance. The only plugs that seem to have the correct teperature range for our trucks are the AC Delco Plats.
Again, I can not state it enough, make use of the search feature in teh forums. It saves a lot of time for you, as this has been discussed Ad Infinitum.

bosch plugs are known to break appart in our engines.

NGK spark plugs seem to work for me................

NKG makes a good plug also, I heard the Iridiums are compatable with our trucks
