I've got a friend looking at a 99 3/4 ton 2wd Cummins w/ 200,000 miles on it. The guy is selling it for 5k. I haven't seen the truck but my friend said that the intake air horn looks black like its been burned or overheated on some of it. Is it possible for the engine to be running hot enough that it discolored the air horn? What else could cause something like this? Thanks

A few educated guess's I would give would be: paint overspray, exhaust leak, small underhood fire (a little less likely but a guess).
