I picked up a Haynes manual for my bravo & from looking at the 1.4 engine pic i found that my bravo engine was missing bits (shaded parts), just would like to know what they are for & if they can cause any probs if there not there? (So far no probs....touch wood) Thanx in advance!

The pipe at the front looks like a warm air feed for the airbox. You should really have this to help warm the car from cold. The large cover would seem to be just cosmetic.
