You'll see that grill on the front of the emitter when the DeLorean's out of the van and in the ILM shots. It's not present in BTTFII, III and some shots in BTTFI; same case with the black-and-orange bulkhead hose; however, missing parts (not replaced or plot-missed) were considered production errors and were left there on the model as this is supposed to be a time machine, not just a mere movie prop. Also, I have to add that the textured interior pictures have a bluish tint because, for some reason, the normals flipped while editing. They've been taken care of since.
